Struct ColorHexView 

pub struct ColorHexView<'a> {
    pub builder: HexViewBuilder<'a>,
    pub color_start: usize,
}

Builder wrapper around a HexViewBuilder that accumulates colored ranges of a hex data dump and renders them via ColorHexView::try_print.

Fields

builder: HexViewBuilder<'a>

The underlying hex view builder that ranges and colors are applied to.

color_start: usize

Running byte offset marking where the next sequentially-added color range begins.

Implementations

impl<'a> ColorHexView<'a>

pub fn new( builder: HexViewBuilder<'a>, colors: Vec<(&'a str, usize)>, ) -> ColorHexView<'a>

Creates a new view from a HexViewBuilder and a list of (color, length) pairs applied sequentially from offset zero.

pub fn add_colors(self, colors: Vec<(&'a str, usize)>) -> ColorHexView<'a>

Appends (color, length) pairs, coloring consecutive byte ranges starting at the current offset and advancing it by each length.

pub fn add_colors_with_range( self, colors: Vec<(&'a str, Range<usize>)>, ) -> ColorHexView<'a>

Applies (color, range) pairs, coloring each explicitly specified byte range of the hex dump.

pub fn try_print(self) -> Result<(), String>

Renders the colored hex view and emits it via log_trace, returning an error string if formatting or UTF-8 conversion fails.
