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 helper also revalidates them. Keep constructor validation so internal callers cannot produce an invalid spec by skipping the executor.

Fields

param: &'static str

value: String

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
