Trait erg_common::traits::Locational

pub trait Locational {
    // Required method
    fn loc(&self) -> Location;

    // Provided methods
    fn ln_begin(&self) -> Option<u32> { ... }
    fn ln_end(&self) -> Option<u32> { ... }
    fn col_begin(&self) -> Option<u32> { ... }
    fn col_end(&self) -> Option<u32> { ... }
}

Required Methods

fn loc(&self) -> Location

NOTE: loc cannot be treated as a light method when self is a large grammatical element. If possible, delay the computation by passing &impl Locational or other means.

Provided Methods

fn ln_begin(&self) -> Option<u32>

1-origin

fn ln_end(&self) -> Option<u32>

fn col_begin(&self) -> Option<u32>

0-origin

fn col_end(&self) -> Option<u32>
