Trait AsMacroCall

pub trait AsMacroCall {
    // Required method
    fn as_call_id_with_errors(
        &self,
        db: &dyn ExpandDatabase,
        krate: CrateId,
        resolver: impl Fn(&ModPath) -> Option<MacroDefId> + Copy,
    ) -> Result<ExpandResult<Option<MacroCallId>>, UnresolvedMacro>;

    // Provided method
    fn as_call_id(
        &self,
        db: &dyn ExpandDatabase,
        krate: CrateId,
        resolver: impl Fn(&ModPath) -> Option<MacroDefId> + Copy,
    ) -> Option<MacroCallId> { ... }
}

A helper trait for converting to MacroCallId

Required Methods

fn as_call_id_with_errors( &self, db: &dyn ExpandDatabase, krate: CrateId, resolver: impl Fn(&ModPath) -> Option<MacroDefId> + Copy, ) -> Result<ExpandResult<Option<MacroCallId>>, UnresolvedMacro>

Provided Methods

fn as_call_id( &self, db: &dyn ExpandDatabase, krate: CrateId, resolver: impl Fn(&ModPath) -> Option<MacroDefId> + Copy, ) -> Option<MacroCallId>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
