An element with expression params.

Required Methods

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

Gets the params.

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

Adds the boxed param.

Provided Methods

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

Adds the boxed param.

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

where E: 'static + Expression,

Adds the param.

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

where E: 'static + Expression,

Adds the param.

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

where L: Into<Literal>,

Adds the literal param.

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

where L: Into<Literal>,

Adds the literal param.

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

Writes the params. (comma separated)

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

Writes the params 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.
