Implementations§
source§impl UnicodeBuffer
impl UnicodeBuffer
sourcepub fn new() -> UnicodeBuffer
pub fn new() -> UnicodeBuffer
Create a new UnicodeBuffer
.
sourcepub fn len(&self) -> usize
pub fn len(&self) -> usize
Returns the length of the data of the buffer.
This corresponds to the number of unicode codepoints contained in the buffer.
sourcepub fn set_pre_context(&mut self, str: &str)
pub fn set_pre_context(&mut self, str: &str)
Sets the pre-context for this buffer.
sourcepub fn set_post_context(&mut self, str: &str)
pub fn set_post_context(&mut self, str: &str)
Sets the post-context for this buffer.
sourcepub fn add(&mut self, codepoint: char, cluster: u32)
pub fn add(&mut self, codepoint: char, cluster: u32)
Appends a character to a buffer with the given cluster value.
sourcepub fn set_direction(&mut self, direction: Direction)
pub fn set_direction(&mut self, direction: Direction)
Set the text direction of the Buffer
’s contents.
sourcepub fn set_script(&mut self, script: Script)
pub fn set_script(&mut self, script: Script)
Set the script from an ISO15924 tag.
sourcepub fn set_language(&mut self, lang: Language)
pub fn set_language(&mut self, lang: Language)
Set the buffer language.
sourcepub fn guess_segment_properties(&mut self)
pub fn guess_segment_properties(&mut self)
Guess the segment properties (direction, language, script) for the current buffer.
sourcepub fn set_flags(&mut self, flags: BufferFlags)
pub fn set_flags(&mut self, flags: BufferFlags)
Set the flags for this buffer.
sourcepub fn flags(&self) -> BufferFlags
pub fn flags(&self) -> BufferFlags
Get the flags for this buffer.
sourcepub fn set_cluster_level(&mut self, cluster_level: BufferClusterLevel)
pub fn set_cluster_level(&mut self, cluster_level: BufferClusterLevel)
Set the cluster level of the buffer.
sourcepub fn cluster_level(&self) -> BufferClusterLevel
pub fn cluster_level(&self) -> BufferClusterLevel
Retrieve the cluster level of the buffer.
sourcepub fn reset_clusters(&mut self)
pub fn reset_clusters(&mut self)
