Enum Column

#[repr(u32)]
pub enum Column {
    Metadata = 0,
    History = 1,
}

GraphQL database tables column ids to the corresponding fuel_core_storage::Mappable table.

Variants

Metadata = 0

The column id of metadata about the relayer storage.

History = 1

The column of the table that stores history of the relayer.

Implementations

impl Column

pub const COUNT: usize = 2usize

The total count of variants in the enum.

pub fn as_u32(&self) -> u32

Returns the usize representation of the Column.

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl EnumCount for Column

const COUNT: usize = 2usize

impl<'_derivative_strum> From<&'_derivative_strum Column> for &'static str

fn from(x: &'_derivative_strum Column) -> &'static str

Converts to this type from the input type.

impl From<Column> for &'static str

fn from(x: Column) -> &'static str

Converts to this type from the input type.

impl Hash for Column

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 Column

fn eq(&self, other: &Column) -> 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 Sequence for Column

const CARDINALITY: usize = 2usize

Number of values of type Self.

fn next(&self) -> Option<Self>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<Self>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<Self>

Returns the first value of type Self.

fn last() -> Option<Self>

Returns the last value of type Self.

impl StorageColumn for Column

fn name(&self) -> String

Returns the name of the column.

fn id(&self) -> u32

Returns the id of the column.

fn as_usize(&self) -> usize

Returns the id of the column as an usize.

impl Copy for Column
