An element with expression parameters.

Required Methods

fn params(&self) -> &[Box<dyn Expression>]

Gets the parameters.

fn add_boxed_param(&mut self, param: Box<dyn Expression>)

Adds the boxed parameter.

Provided Methods

fn with_boxed_param(self, param: Box<dyn Expression>) -> Self

Adds the boxed parameter.

fn add_param<E>(&mut self, param: E)

where E: 'static + Expression,

Adds the parameter.

fn with_param<E>(self, param: E) -> Self

where E: 'static + Expression,

Adds the parameter.

fn add_literal_param<L>(&mut self, literal: L)

where L: Into<Literal>,

Adds the literal parameter.

fn with_literal_param<L>(self, literal: L) -> Self

where L: Into<Literal>,

Adds the literal parameter.

fn write_params(&self, b: &mut CodeBuffer)

Writes the parameters. (comma separated)

fn write_params_with_parens(&self, b: &mut CodeBuffer)

Writes the parameters with parentheses. (comma separated)

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.
