Enum MediaError 

pub enum MediaError {
    Unreadable(String),
    Undecodable(String),
    TooLarge {
        width: u32,
        height: u32,
    },
}

Why a block has no pixels. Every variant is a placeholder plus alt text outcome, never a panic and never a stall.

Variants

Unreadable(String)

The file is not there, or is not readable.

Undecodable(String)

Read fine, but no decoder recognised it.

TooLarge

Bigger than MAX_PIXELS. Refused before allocating, so a pathological or hostile image cannot exhaust memory.

Fields

width: u32

height: u32
