Methods

impl InputAt

pub fn is_start(&self) -> bool

Returns true iff this position is at the beginning of the input.

pub fn is_end(&self) -> bool

Returns true iff this position is past the end of the input.

pub fn char(&self) -> Char

Returns the character at this position.

If this position is just before or after the input, then an absent character is returned.

pub fn byte(&self) -> Option<u8>

Returns the byte at this position.

pub fn len(&self) -> usize

Returns the UTF-8 width of the character at this position.

pub fn is_empty(&self) -> bool

Returns whether the UTF-8 width of the character at this position is zero.

pub fn pos(&self) -> usize

Returns the byte offset of this position.

pub fn next_pos(&self) -> usize

Returns the byte offset of the next position in the input.
