Struct Statement

pub struct Statement {
    pub value: StatementEnum,
    pub span: Span,
}

The statement type.

Fields

value: StatementEnum

The type of statement.

span: Span

The location of the statement.

Implementations

impl Statement

pub fn expect<T>(&self) -> Result<T>

where StatementEnum: AsVariant<T>, T: Clone,

Downcast this statement to its inner type. Returns an ErrorType::UnexpectedStatement when T is not the type of the inner statement.

Examples

use vyder_core::prelude::*;

let statement: Statement = Statement { value: statements::Break.into(), span: Span::new_with_end((1, 1, 0), (1, 6, 5), "example") };
assert!(statement.expect::<statements::Return>().is_err());
let _: statements::Break = statement.expect::<statements::Break>().unwrap();

Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Statement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Statement

fn eq(&self, other: &Statement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
