Struct Asset 

pub struct Asset {
    pub id: String,
    pub media_type: String,
    pub bytes: Vec<u8>,
    pub width_px: Option<u32>,
    pub height_px: Option<u32>,
    pub dpi: Option<f32>,
}

An image file found in a manuscript, referenced by Block::Image::asset. An image file, e.g. assets/image1.png in a project.

Fields

id: String

File name under assets/ in the project, e.g. image1.png.

media_type: String

bytes: Vec<u8>

width_px: Option<u32>

Pixel size from the file header, if it could be read.

height_px: Option<u32>

dpi: Option<f32>

Resolution stored in the file (PNG pHYs, JPEG JFIF), if any.

Implementations

impl Asset

pub fn new(id: impl Into<String>, bytes: Vec<u8>) -> Asset

An asset with metadata read from bytes. Content that is not a supported image gets application/octet-stream and no size.

pub fn is_valid_id(id: &str) -> bool

Whether id can be used as a file name under assets/: a plain name (no directories, no .., no leading dot) of portable characters.
