Struct brane_ast::TextPos

pub struct TextPos {
    pub line: usize,
    pub col: usize,
}

Defines a position in the input text.

Fields

line: usize

The y-coordinate of the position (one-indexed)

col: usize

The x-coordinate of the position (one-indexed)

Implementations

impl TextPos

pub const fn new(line: usize, col: usize) -> TextPos

Constructor for the TextPos.

Arguments

• line: The line number.
• col: The column number.

Returns

A new TextPos instance with the given line and column number.

pub const fn none() -> TextPos

Constructor for the TextPos that initializes it to ‘none’.

Returns

A new TextPos instance that represents ‘no position’.

pub fn end_of<T, X>(span: &LocatedSpan<T, X>) -> TextPos

where T: AsBytes,

Constructor for the TextPos that initializes it to the end of the given Span.

Concretely, it adds the length of the span to the Span’s start location, modulo any newlines (‘\n’) it finds.

Generic types

• T: The type stored in the LocatedSpan.
• X: Any extra information stored in the span.

Arguments

• span: The LocatedSpan that contains both the text and position that we will use to compute the end position.

Returns

A new TextPos instance that points to the end of the span (inclusive).

pub const fn is_some(&self) -> bool

Returns if this TextPos is a position (i.e., does not represent ‘no position’).

Returns

Whether or not this TextPos represents a useable position (true) or if it is ‘no position’ (false).

pub const fn is_none(&self) -> bool

Returns if this TextPos is not a position (i.e., represents ‘no position’).

Returns

Whether or not this TextPos represents a useable position (false) or if it is ‘no position’ (true).
