Struct GcBuf 

pub struct GcBuf(/* private fields */);

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

See Gc for more details.

Implementations

impl GcBuf

pub 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.

pub fn as_gc(&self) -> &Gc

Returns a borrowed grapheme cluster slice.

Methods from Deref<Target = Gc>

pub fn len(&self) -> usize

Returns the length of this grapheme cluster in bytes.

pub 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.

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

Converts this to a byte slice.

pub fn as_str(&self) -> &str

Converts this to a string slice.

pub fn base_char(&self) -> char

Returns the “base” code point.

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

pub 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.

pub 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.

pub fn chars(&self) -> Chars<'_>

An iterator over the code points of this grapheme cluster.

pub fn char_indices(&self) -> CharIndices<'_>

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

pub fn bytes(&self) -> Bytes<'_>

An iterator over the bytes of this grapheme cluster.

pub fn to_lowercase(&self) -> ToLowercase<'_>

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

pub fn to_uppercase(&self) -> ToUppercase<'_>

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