pub trait UnicodeWidthStr: Sealed {
// Required methods
fn width(&self) -> usize;
fn width_cjk(&self) -> usize;
}Expand description
Methods for determining displayed width of Unicode strings.
Required Methods§
Sourcefn width(&self) -> usize
fn width(&self) -> usize
Returns the string’s displayed width in columns.
This function treats characters in the Ambiguous category according to Unicode Standard Annex #11 as 1 column wide. This is consistent with the recommendations for non-CJK contexts, or when the context cannot be reliably determined.
Sourcefn width_cjk(&self) -> usize
fn width_cjk(&self) -> usize
Returns the string’s displayed width in columns.
This function treats characters in the Ambiguous category according to Unicode Standard Annex #11 as 2 column wide. This is consistent with the recommendations for CJK contexts.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
