Struct BadgeInfo 

pub struct BadgeInfo {
    pub key: &'static str,
    pub official: bool,
    pub required: &'static [&'static str],
    pub optional: &'static [&'static str],
}

A badge key cargo-readme understands, plus which attributes it reads.

This is the single source of truth behind cargo readme --list-badges. The keys here must stay in sync with the match arms in [super::manifest::process_badges]; a unit test in that module enforces it.

Fields

key: &'static str

The [badges] table key, e.g. "coveralls".

official: bool

Whether crates.io documents this badge in the manifest reference.

required: &'static [&'static str]

Attributes that must be present, or badge rendering fails.

optional: &'static [&'static str]

Attributes that are read when present, otherwise defaulted.
