Enum PrecedenceEntry 

pub enum PrecedenceEntry {
    Name(String),
    Rule(String),
}

One entry of a precedence order: a named precedence or a rule, whose productions it ranks.

Variants

Name(String)

The precedence namedPrecedence gives this name.

Rule(String)

Every precedence of this rule’s productions.

Implementations

impl PrecedenceEntry

pub fn from_kind(kind: &str, value: String) -> Option<Self>

Builds an entry from its kind word, name or rule, and its value.

pub const fn kind(&self) -> &'static str

The entry’s kind word, name or rule.

pub fn value(&self) -> &str

The precedence or rule name.
