Struct strcursor::grapheme::GcBuf

pub struct GcBuf(_);

An owned, single Unicode grapheme cluster (akin to String).

See Gc for more details.

Methods

impl GcBuf

unsafe fn from_string_unchecked(s: String) -> GcBuf

Create a new GcBuf from the given String.

This function does not check to ensure the provided string is a single, valid grapheme cluster.

fn as_gc(&self) -> &Gc

Returns a borrowed grapheme cluster slice.

Methods from Deref<Target=Gc>

fn len(&self) -> usize

Returns the length of this grapheme cluster in bytes.

fn has_marks(&self) -> bool

Does this grapheme cluster have additional marks applied to it?

This is true if the cluster is comprised of more than a single code point.

fn as_bytes(&self) -> &[u8]

Converts this to a byte slice.

fn as_str(&self) -> &str

Converts this to a string slice.

fn base_char(&self) -> char

Returns the "base" code point.

That is, this returns the first code point in the cluster.

fn base(&self) -> &Gc

Returns the "base" code point as a grapheme cluster.

This is equivalent to converting this GC into a string slice, then slicing off the bytes that make up the first code point.

fn mark_str(&self) -> &str

Returns the combining marks as a string slice.

The result of this method may be empty, or of arbitrary length.

fn chars(&self) -> Chars

An iterator over the code points of this grapheme cluster.

fn char_indices(&self) -> CharIndices

An iterator over the code points of this grapheme cluster, and their associated byte offsets.

fn bytes(&self) -> Bytes

An iterator over the bytes of this grapheme cluster.

fn to_lowercase(&self) -> ToLowercase

Returns an iterator over the code points in the lower case equivalent of this grapheme cluster.

fn to_uppercase(&self) -> ToUppercase

Returns an iterator over the code points in the upper case equivalent of this grapheme cluster.
