Enum CompatibilityMode 

#[non_exhaustive]
pub enum CompatibilityMode {
    Default,
    Strict,
}

Compatibility mode that governs argv parsing + rendering rules.

In Default mode the CLI behaves like a modern Rust-native tool (UTF-8 input, color flags accepted, ergonomic clap diagnostics). In Strict mode the binary mirrors upstream figlet 2.2.5 byte-for-byte (Latin-1 clamped input, color flags rejected, hand-rolled getopt-style diagnostics) so existing shell scripts that target upstream figlet run unmodified.

Marked #[non_exhaustive] so future modes (e.g. Toilet) remain a non-breaking addition.

use rusty_figlet::CompatibilityMode;

let mode = CompatibilityMode::default();
assert_eq!(mode, CompatibilityMode::Default);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

Modern, Rust-native behavior (UTF-8 input, color enabled, ergonomic diagnostics).

Strict

Byte-equal upstream figlet 2.2.5 behavior (Latin-1 input, color flags rejected, getopt-style diagnostics).

Trait Implementations

impl Clone for CompatibilityMode

fn clone(&self) -> CompatibilityMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompatibilityMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CompatibilityMode

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CompatibilityMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompatibilityMode

fn eq(&self, other: &CompatibilityMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
