Struct parse_js::source::SourceRange

pub struct SourceRange<'a> {
    pub source: &'a [u8],
    pub edit: Option<&'a [u8]>,
    pub start: usize,
    pub end: usize,
}

A string backed by a source. Treated as a string, so contents rather than position is considered the value. It’s illegal to operate on two SourceRange values from different sources, like Add or Eq. Adding two SourceRange (Add, AddAssign, add_option, etc.) values is illegal if at least one has an edit, due to ambiguity. Performing these illegal actions may result in a panic.

Fields

source: &'a [u8]

edit: Option<&'a [u8]>

start: usize

end: usize

Trait Implementations

impl<'a> Add<SourceRange<'a>> for SourceRange<'a>

type Output = SourceRange<'a>

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl<'a> AddAssign<SourceRange<'a>> for SourceRange<'a>

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl<'a> Clone for SourceRange<'a>

fn clone(&self) -> SourceRange<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SourceRange<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for SourceRange<'a>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Index<SourceRange<'a>> for Lexer<'a>

type Output = [u8]

The returned type after indexing.

fn index(&self, index: SourceRange<'a>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a> PartialEq<&str> for SourceRange<'a>

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

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

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

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

impl<'a> PartialEq<SourceRange<'a>> for SourceRange<'a>

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

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

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

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