Enum FmtDebug 

pub enum FmtDebug {
    Full,
    Shallow,
    None,
}

Values for the -Z fmt-debug flag.

Variants

Full

Derive fully-featured implementation

Shallow

Print only type name, without fields

None

#[derive(Debug)] and {:?} are no-ops

Implementations

impl FmtDebug

pub(crate) fn all() -> [Symbol; 3]

Trait Implementations

impl Clone for FmtDebug

fn clone(&self) -> FmtDebug

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FmtDebug

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

Formats the value using the given formatter.

impl DepTrackingHash for FmtDebug

fn hash( &self, hasher: &mut StableHasher, _: ErrorOutputType, _for_crate_hash: bool, )

impl Hash for FmtDebug

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 FmtDebug

fn eq(&self, other: &FmtDebug) -> 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.

impl Copy for FmtDebug

impl StructuralPartialEq for FmtDebug

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
