Expand description

Methods for determining displayed width of Unicode strings.

Required Methods§

source

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.

source

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.
