Trait Measured 

pub trait Measured {
    const TEXT: bool;

    // Required method
    fn size(&self) -> Option<i64>;

    // Provided method
    fn is_blank(&self) -> bool { ... }
}

Required Associated Constants

const TEXT: bool

Required Methods

fn size(&self) -> Option<i64>

Provided Methods

fn is_blank(&self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
