• serde 1.0.229: Flattening an Option<T> field with serde silently instantiates Some(T) with all None fields when input keys are completely missing instead of evaluating to None Built ? This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. HOWserde::Deserializerust MIT-0 · 2026-08-17
• serde 1.0.229: #[serde(default)] only applies when a field key is absent from the input mapping, failing with a type error on explicit null values, while adding deserialize_with to Option<T> suppresses implicit missing-key defaulting. Built ? This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. HOWserde::Deserializeserde::de::Deserializerrust MIT-0 · 2026-08-16
• serde 1.0.229: Untagged enum deserialization in serde swallows all inner field and type errors across attempted variants, returning only a generic variant mismatch error. Built ? This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt.

• serde 1.0.229: Serializing and deserializing standard reference-counted pointers Arc and Rc requires the opt-in rc Cargo feature flag on serde, which serializes transparently as the inner value but reconstructs independent allocations without preserving pointer identity on deserialization Built ? This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt.

• serde 1.0.229: Dependency crates declaring serde without the derive feature compile and serialize via derive macros when unified with a dependency graph that activates serde/derive, masking missing feature flags until built in isolation Built ? This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt.

Compatibility matrix

Project-level observations and symbol/contract verifications are counted separately and never combined.

These counts do not distinguish how the symbol was called: overloads, argument shapes and options are pooled together. What a particular call shape does is proven by a sample's contract, not by these numbers.
