Release Notes

bourumir-wyngs/serde-saphyr (serde-saphyr)

v2.1.0

Compare Source

Added

• Added PropertySyntax::DockerComposeWithNulls: Compose interpolation where a value that is
  solely a reference to an unset property, or whose expansion is null/~, becomes YAML null.
  Explicitly empty properties and empty defaults stay empty strings, and DockerCompose itself
  is unchanged.
• Added opt-in Options::reject_tagged_field_names to catch misplaced tags on
  struct field names, with Error::TaggedStructFieldName diagnostics. Struct field names can
  only be strings, !!str is still accepted. As other tags can only be ignored, tag on a structure
  field name is almost for sure placed wrongly. This setting will be default in next major release.
• Added Options::leading_zero_numbers_as_strings and
  Options::underscored_numbers_as_strings to preserve numeric spellings such as
  0755 and 1_000 as strings in untyped values, including untagged enums and
  flattened fields (#​225).
  Both default to false; direct typed parsing, explicit numeric tags, and
  mapping-key comparison keep their existing behavior.
• Added Error::render_to to append diagnostics to any std::fmt::Write using
  RenderOptions, without collecting the complete output in an intermediate string
  (#​221).
• Added DuplicateKeyPolicy::PassThrough to delegate repeated explicit mapping entries
  to Serde visitors, matching serde_yaml's handling for structs, standard maps, and custom
  multimap visitors (#​226).
  The default remains Error; merge expansion retains its precedence rules. See the README
  migration note for the scope of this option.

Deprecated

• Deprecated SerializerOptions::empty_as_braces. Setting it to false emits YAML null
  for empty block collections without tags or anchors. These values do not round-trip into
  collection types. Omit the setting to keep the default true and emit [] or {}.
  Existing serialization behavior remains supported for compatibility.

Fixed

• Preserve application-tagged null-like documents in multi-document APIs, including
  the garde and validator integrations. A document such as !Maybe null now reaches
  enum dispatch instead of being skipped. This also affects default options: an
  Option<String> target receives a None item for !Foo null, while a String target
  reports NullIntoString. Untagged null documents and explicit !!null are still skipped.
• Resolve tagged enum payloads according to their target type under no_schema:
  !Number 42 can deserialize into a numeric payload, while a string payload still
  requires quoting, as in !Text "42". This applies independently of property interpolation.
• Keep validated and ordinary multi-document APIs consistent for interpolated nulls
  and interpolation work budgets. Reader iterators stop after an interpolation-budget
  breach, including breaches reported through an alias.
• Emit empty lines in literal and folded block scalars without indentation,
  avoiding trailing whitespace while preserving whitespace in the string content
  (#​249).
• Expose the original std::io::Error from deserialization failures through
  std::error::Error::source(). The outer message is IO error, so error chains
  include the underlying cause only once. Standalone Miette, Figment, and Figment2
  diagnostics retain the cause in their messages. Custom Miette formatters retain
  control over the complete message through MessageFormatter::format_standalone_message.
• Avoid duplicate messages from Error::WithSnippet when following
  std::error::Error::source() by forwarding the wrapped error's source.
  Use without_snippet() to inspect the wrapped error. Alias errors retain their
  complete source chain, including snippet wrappers, for compatibility.
• Validate recognized scalar tags consistently for numeric, boolean, character,
  and enum targets, including externally tagged enum mapping keys (#​235).
  Incompatible tags and tagged null-like payloads no longer bypass validation.
• Apply enabled robotics conversions to untyped reads, skipped fields, and
  flattened values. The local !time duration tag is distinct from standard YAML
  !!timestamp; robotics tags require the feature and angle_conversions: true.
• Reject YAML null when deserializing sequences, mappings, and mapping-based structs instead
  of silently constructing empty values (#​233).
  Blank values and the plain spellings ~, null, Null, and NULL are handled consistently.
  Write [] for an empty sequence or {} for an empty mapping. Option<T> null handling
  and defaults for absent fields are unchanged; see the README migration notes.
• Reject "wrong case" YAML 1.2 Core spellings like NUlL, .NAn or FAlse (PR #​254, #​237).
