Enum cursive::utils::span::IndexedCow

pub enum IndexedCow {
    Borrowed {
        start: usize,
        end: usize,
    },
    Owned(String),
}

A span of text that can be either owned, or indexed in another String.

Variants

Borrowed

Indexes content in a separate string.

Fields of Borrowed

start: usize

Byte offset of the beginning of the span (inclusive)

end: usize

Byte offset of the end of the span (exclusive)

Owned(String)

Owns its content.

Implementations

impl IndexedCow

pub fn resolve(&'a self, source: &'a str) -> &'a str

Resolve the span to a string slice.

pub fn from_cow(cow: Cow<str>, source: &str) -> IndexedCow

Returns an indexed view of the given item.

Note: it is assumed cow, if borrowed, is a substring of source.

pub fn is_empty(&self) -> bool

Returns true if this represents an empty span.

pub fn offset(&mut self, offset: usize)

If self is borrowed, offset its indices by the given value.

Useful to update spans when concatenating sources.

Trait Implementations

impl<T> AsRef<IndexedCow> for IndexedSpan<T>

fn as_ref(&self) -> &IndexedCow

Performs the conversion.

impl Clone for IndexedCow

fn clone(&self) -> IndexedCow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IndexedCow

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

Formats the value using the given formatter.

impl Eq for IndexedCow

impl PartialEq<IndexedCow> for IndexedCow

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

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

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

This method tests for !=.
