Enum SnapInstallError 

pub enum SnapInstallError {
    InvalidArg {
        param: &'static str,
        value: String,
    },
}

Returned when snap_install’s name or channel fails validation.

Variants

InvalidArg

name/channel contains a shell metacharacter or otherwise fails the safe-arg allowlist. Carries the offending parameter and value.

Defense in depth: the executor already validates both via validated_safe_arg before calling this constructor, but the auto_update: false path interpolates name/channel into a sh -c "snap install … && snap refresh --hold …" fragment — a future internal Rust caller (fleet plan/execute path) that skipped the executor could not otherwise be blocked from injecting through it.

Fields

param: &'static str

value: String
