Expand description

Callbacks to build usage-context-specific evaluation objects from AST nodes.

This is used to implement different meanings of self or different globally available functions in the template language depending on the context in which it is invoked.

Required Associated Types§

Source

type Property: CoreTemplatePropertyVar<'a> + 'a

Required Methods§

Source

fn settings(&self) -> &UserSettings

Source

fn current_dir(&self) -> &Path

Returns the working directory for filesystem path template methods.

Source

fn build_function( &self, diagnostics: &mut TemplateDiagnostics, build_ctx: &BuildContext<'_, Self::Property>, function: &FunctionCallNode<'_>, ) -> TemplateParseResult<Self::Property>

Translates the given global function call to a property.

This should be delegated to CoreTemplateBuildFnTable::build_function().

Source

fn build_method( &self, diagnostics: &mut TemplateDiagnostics, build_ctx: &BuildContext<'_, Self::Property>, property: Self::Property, function: &FunctionCallNode<'_>, ) -> TemplateParseResult<Self::Property>

Creates a method call thunk for the given function of the given property.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
