Struct Span 

pub struct Span {
    pub start: u32,
    pub end: u32,
}

A byte-offset range within a TOML document.

Convertible to and from Range<u32> and Range<usize>.

Fields

start: u32

Start byte offset (inclusive).

end: u32

End byte offset (exclusive).

Implementations

impl Span

pub fn new(start: u32, end: u32) -> Self

Creates a new Span from start and end byte offsets.

pub fn range(self) -> Range<usize>

Converts this span into a Range<usize>.

pub fn is_empty(&self) -> bool

Returns true if both start and end are zero.

pub fn grow_key_to_header(&mut self, text: &[u8])

Grows a key span to cover the full header brackets.

For [a.b.c] with a key span on b, produces the span of [a.b.c]. Handles [[aot]] as well.

pub fn extract_header_span(&self, text: &[u8]) -> Span

Extracts the header-line span from a HEADER table span.

The HEADER span covers [ through the last body value. This returns just the [key.path] or [[aot]] portion.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate 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 Default for Span

fn default() -> Span

Returns the “default value” for a type.

impl From<Range<u32>> for Span

fn from(s: Range<u32>) -> Self

Converts to this type from the input type.

impl From<Span> for (u32, u32)

fn from(s: Span) -> (u32, u32)

Converts to this type from the input type.

impl From<Span> for (usize, usize)

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

Converts to this type from the input type.

impl From<Span> for Range<u32>

fn from(s: Span) -> Self

Converts to this type from the input type.

impl From<Span> for Range<usize>

fn from(s: Span) -> Self

Converts to this type from the input type.

impl PartialEq for Span

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