Struct dockerfile_parser::Span

pub struct Span {
    pub start: usize,
    pub end: usize,
}

A byte-index tuple representing a span of characters in a string

Fields

start: usize

end: usize

Implementations

impl Span

pub fn new(start: usize, end: usize) -> Span

pub fn relative_span(&self, dockerfile: &Dockerfile) -> (usize, Span)

Determines the 0-indexed line number and line-relative position of this span.

A reference to the Dockerfile is necessary to examine the original input string. Note that if the original span crosses a newline boundary, the relative span's end field will be larger than the line length.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl Eq for Span

impl From<(usize, usize)> for Span

fn from(tup: (usize, usize)) -> Span

Performs the conversion.

impl PartialEq<Span> for Span

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

This method tests for self and other values to be equal, and is used by ==.
