Enum NamespaceQualifierBinding 

pub enum NamespaceQualifierBinding {
    Unaliased,
    Bound {
        components: Vec<String>,
        global: bool,
        lexical_scope: Vec<String>,
        depth: usize,
    },
    Unresolved {
        depth: usize,
    },
}

How the namespace aliases in effect at a reference rebind its qualifier.

Variants

Unaliased

No namespace alias binds a qualifier component at the reference.

Bound

The qualifier names an alias whose target, followed through any alias chain, is established: look components up from lexical_scope, the scope of the last alias in the chain.

Fields

components: Vec<String>

global: bool

lexical_scope: Vec<String>

depth: usize

Unresolved

The qualifier names an alias whose target cannot be established here.

Fields

depth: usize

Implementations

impl NamespaceQualifierBinding

pub fn depth(&self) -> Option<usize>

The lexical depth at which the first alias binds: the length of the scope that declares it, or one more than the reference’s scope for a block-scope alias. An ordinary name found at a deeper tier shadows it.
