Enum FeatureOverride 

#[non_exhaustive]
pub enum FeatureOverride {
    EnumType(EnumTypeOverride),
}

A path-scoped protobuf editions feature override, applied by mutating the parsed descriptors before generation (see feature_overrides).

Editions unification models proto2 and proto3 as editions with fixed feature defaults, so an override’s semantics are “what this proto would say had it been migrated to editions and this feature set at this path”. Each variant is admitted only once buffa’s codegen, runtime, and validation handle the descriptor states it can create — the enum is the allowlist. Overrides never change the wire format.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EnumType(EnumTypeOverride)

Override features.enum_type for matching enums or enum fields.

An enum-type path mutates the enum’s own descriptor (a spec-valid editions construct that also flows into the embedded reflection pool); a field path injects a field-level override honored by buffa’s feature resolution only (enum_type is not a legal field target, so other runtimes reading the exported descriptors ignore it).

Implementations

impl FeatureOverride

pub fn feature_name(&self) -> &'static str

The editions feature name this override sets, as spelled in google.protobuf.FeatureSet (e.g. for diagnostics).

pub fn value_name(&self) -> &'static str

The feature value this override sets, as spelled in the descriptor enum (e.g. for diagnostics).
