Graphic

Struct Graphic 

Source
pub struct Graphic<'a> {
    pub filename: &'a str,
    pub data_lines: Vec<&'a str>,
    pub span: Span,
}
Expand description

Embedded graphic from [Graphics\] section

Represents an image file embedded in the ASS script using UU-encoding. Commonly used for logos, textures, and other graphical elements. Provides lazy decoding for performance.

§Examples

use ass_core::parser::ast::{Graphic, Span};

let graphic = Graphic {
    filename: "logo.png",
    data_lines: vec!["begin 644 logo.png", "M89PNG..."],
    span: Span::new(0, 0, 0, 0),
};

let decoded = graphic.decode_data()?;

Fields§

§filename: &'a str

Graphic filename as it appears in the [Graphics\] section

§data_lines: Vec<&'a str>

UU-encoded graphic data lines as zero-copy spans

§span: Span

Span in source text where this graphic is defined

Implementations§

Source§

impl Graphic<'_>

Source

pub fn decode_data(&self) -> Result<Vec<u8>, CoreError>

Decode UU-encoded graphic data with lazy evaluation

Converts the UU-encoded data lines to raw binary image data. This is expensive so it’s only done when explicitly requested.

§Returns

Decoded binary image data on success, error if UU-decoding fails

§Errors

Returns an error if the UU-encoded data is malformed or cannot be decoded.

Source

pub fn to_ass_string(&self) -> String

Convert graphic to ASS string representation

Generates the graphic entry as it appears in the [Graphics\] section.

§Examples
let graphic = Graphic {
    filename: "logo.png",
    data_lines: vec!["begin 644 logo.png", "M'XL...", "end"],
    span: Span::new(0, 0, 0, 0),
};
let ass_string = graphic.to_ass_string();
assert!(ass_string.starts_with("filename: logo.png\n"));
assert!(ass_string.contains("M'XL..."));
Source

pub fn validate_spans(&self, source_range: &Range<usize>) -> bool

Available on debug-assertions enabled only.

Validate all spans in this Graphic reference valid source

Debug helper to ensure zero-copy invariants are maintained. Validates that filename and all data line references point to memory within the specified source range.

Only available in debug builds to avoid performance overhead.
