Struct FlagSpec 

#[non_exhaustive]
pub struct FlagSpec {
    pub name: String,
    pub kind: FlagKind,
    pub help: Option<String>,
    pub values: Option<Vec<String>>,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

e.g. --mode, --json, -q.

kind: FlagKind

Boolean / enum / free-string discriminator. See FlagKind.

help: Option<String>

clap help text.

values: Option<Vec<String>>

For kind == FlagKind::Enum: the accepted values, harvested from clap’s PossibleValuesParser. Owned (not &'static) so the helper works for any future enum flag, not just --mode (see #215).
