Struct conrod_core::text::line::Info

pub struct Info {
    pub start_byte: usize,
    pub start_char: usize,
    pub end_break: Break,
    pub width: Scalar,
}

Information about a single line of text within a &str.

Info is a minimal amount of information that can be stored for efficient reasoning about blocks of text given some &str. The start and end_break can be used for indexing into the &str, and the width can be used for calculating line Rects, alignment, etc.

Fields

start_byte: usize

The index into the &str that represents the first character within the line.

start_char: usize

The character index of the first character in the line.

end_break: Break

The index within the &str at which this line breaks into a new line, along with the index at which the following line begins. The variant describes whether the break is caused by a Newline character or a Wrap by the given wrap function.

width: Scalar

The total width of all characters within the line.

Implementations

impl Info

pub fn end_byte(&self) -> usize

The end of the byte index range for indexing into the slice.

pub fn end_char(&self) -> usize

The end of the index range for indexing into the slice.

pub fn byte_range(self) -> Range<usize>

The index range for indexing (via bytes) into the original str slice.

pub fn char_range(self) -> Range<usize>

The index range for indexing into a char iterator over the original str slice.

Trait Implementations

impl Copy for Info

impl Debug for Info

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Info> for Info

fn eq(&self, other: &Info) -> bool
