Struct svgdom::StrSpan

#[must_use]
pub struct StrSpan<'a> { /* fields omitted */ }

An immutable string slice.

Unlike &str contains a reference to the original string and a span position.

Methods

impl<'a> StrSpan<'a>

pub fn from_substr(text: &str, start: usize, end: usize) -> StrSpan

Constructs a new StrSpan from substring.

pub fn start(&self) -> usize

Returns a start position of the span.

pub fn end(&self) -> usize

Returns a end position of the span.

pub fn len(&self) -> usize

Returns a length of the span.

pub fn is_empty(&self) -> bool

Returns a length of the span.

pub fn full_len(&self) -> usize

Returns a length of the span underling string.

pub fn to_str(&self) -> &'a str

Returns a span slice.

A bit expensive, since Rust checks for char boundary.

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn as_bytes(&self) -> &'a [u8]

Returns a span slice as bytes.

The same as to_str but does not involve char boundary checking.

pub fn slice_region(&self, start: usize, end: usize) -> StrSpan<'a>

Returns an underling string region as StrSpan.

pub fn full_str(&self) -> &'a str

Returns an underling string.

pub fn trim(&self) -> StrSpan<'a>

Returns a trimmed version of this StrSpan.

Removes only leading and trailing spaces.

This function will trim escaped spaces (aka  ) too.
