Trait Implementations

impl CoreArrayProvider for Metadata

type Raw = *mut BNMetadata

type Context = ()

type Wrapped<'a> = Guard<'a, Metadata>

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Display for Metadata

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

Formats the value using the given formatter.

impl IntoJson for &Metadata

type Output = BnString

fn get_json_string(self) -> Result<BnString, ()>

impl PartialEq for Metadata

fn eq(&self, other: &Self) -> 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 ToOwned for Metadata

type Owned = Ref<Metadata>

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
