Trait FromParams

pub trait FromParams<'js>: Sized {
    // Required methods
    fn param_requirements() -> ParamRequirement;
    fn from_params<'a>(params: &mut ParamsAccessor<'a, 'js>) -> Result<Self>;
}

A trait to extract a tuple of argument values.

Required Methods

fn param_requirements() -> ParamRequirement

The parameters requirements this value requires.

fn from_params<'a>(params: &mut ParamsAccessor<'a, 'js>) -> Result<Self>

Convert from a parameter value.

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.
