Struct ExtensionRegistry 

pub struct ExtensionRegistry { /* private fields */ }

Merged, extends-resolved extension registry.

Implementations

impl ExtensionRegistry

pub fn load( defaults: &Path, project: Option<&Path>, ) -> Result<Self, ExtensionError>

Load shipped defaults and an optional project registry, then merge.

Later files override earlier entries by id (in-place). extends is resolved after merge. User config (~/.config/wyvern/extensions.json) is not loaded in Phase F.

Errors

Returns ExtensionError::InvalidRegistry for unreadable or invalid JSON.

pub fn load_default() -> Result<Self, ExtensionError>

Load shipped defaults plus .wyvern/extensions.json from the cwd.

Errors

Returns ExtensionError::InvalidRegistry when a registry file is invalid.

pub fn from_json_str(json: &str) -> Result<Self, ExtensionError>

Parse a registry from an in-memory JSON string (tests and shipped fallback).

Errors

Returns ExtensionError::InvalidRegistry when json is not a v1 registry.

pub fn match_argv<'a>( &'a self, argv: &'a [String], ) -> Option<ExtensionMatch<'a>>

Walk merged extensions in order; first match wins.

After extends resolution, an extension whose preexec.requires binaries are absent on PATH does not match (fallthrough).

pub fn match_argv_with<'a>( &'a self, argv: &'a [String], probe: &dyn RequiresProbe, ) -> Option<ExtensionMatch<'a>>

Self::match_argv with an injectable RequiresProbe.

pub fn match_with_diagnostics<'a>( &'a self, argv: &'a [String], ) -> MatchOutcome<'a>

Match argv and record extensions skipped for missing requires.

pub fn match_with_diagnostics_with<'a>( &'a self, argv: &'a [String], probe: &dyn RequiresProbe, ) -> MatchOutcome<'a>

Self::match_with_diagnostics with an injectable RequiresProbe.

pub fn extensions(&self) -> &[ExtensionDef]

Merged extensions in match order.
