Struct IntegerLiteral 

pub struct IntegerLiteral { /* private fields */ }

A typed Macaulay2 integer_literal syntax leaf.

Implementations

impl IntegerLiteral

pub fn new(text: impl AsRef<str>, span: Span) -> Self

Creates a leaf from its text and source span.

pub fn text(&self) -> &str

Returns the leaf spelling by slicing its source span.

Examples found in repository

examples/type_inference.rs (line 242)

    fn integer(&self, literal: &IntegerLiteral) -> DemoFact {
        Self::known(
            vec![DemoType::Integer, DemoType::Number, DemoType::Thing],
            literal.text().parse().ok().map(DemoValue::Integer),
        )
    }

pub fn set_text(&mut self, text: impl AsRef<str>)

Replaces the leaf spelling with a newly source-backed fragment.
