Trait const_gen::CompileConst

Trait which defines how a type should be represented as a constant

Required methods

fn const_type() -> String

Get a string representation of a type. This must be implemented for each type. Note that this is not necessarily a representation of the ACTUAL type, but rather the type that should be used if this data is going to be represented as a compile-time constant.

fn const_val(&self) -> String

Get a string representation of the current value in constant form.

Provided methods

fn const_declaration(&self, name: &str) -> String

Takes a string (a SCREAMING_SNAKE_CASE string is preferred) to use as a constant name, then calls self.const_type() and self.const_val() in order to generate a Rust compile-time constant declaration statement.

fn const_definition(_attrs: &str) -> String

Return a const definition for this type. Attributes may be included, and must be formatted as the compiler would expect to see them (including the pound sign and square brackets "#[...]"). Always returns an empty string for types defined in the standard library. Typically this is easier to call instead through the const_definition! macro.
