Trait FromArgument 

pub trait FromArgument<'a, 'cx>: Sized {
    type Config;

    // Required method
    fn from_argument(
        accessor: &'a mut Accessor<'_, 'cx>,
        config: Self::Config,
    ) -> Result<Self>;
}

Required Methods

fn from_argument( accessor: &'a mut Accessor<'_, 'cx>, config: Self::Config, ) -> Result<Self>

Converts from an argument.

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.
