Trait Scoper 

pub trait Scoper: Send + Sync {
    // Required method
    fn scope_raw<'viewee>(
        &self,
        input: &'viewee str,
    ) -> RangesWithContext<'viewee>;

    // Provided method
    fn scope<'viewee>(&self, input: &'viewee str) -> ROScopes<'viewee> { ... }
}

An item capable of scoping down a given input into individual scopes.

Required Methods

fn scope_raw<'viewee>(&self, input: &'viewee str) -> RangesWithContext<'viewee>

Scope the given input, returning raw ranges.

Raw ranges are those not turned into ROScopes yet.

Provided Methods

fn scope<'viewee>(&self, input: &'viewee str) -> ROScopes<'viewee>

Scope the given input.

After application, the returned scopes are a collection of either in-scope or out-of-scope parts of the input. Assembling them back together should yield the original input.

Implementations on Foreign Types

impl Scoper for &[Box<dyn LanguageScoper>]

fn scope_raw<'viewee>(&self, input: &'viewee str) -> RangesWithContext<'viewee>

Allows multiple scopers to be applied all at once.

They are OR’d together in the sense that if any of the scopers hit, a position/range is considered in scope. In some sense, this is the opposite of ScopedViewBuilder::explode, which is subtractive.
