Struct diesel::pg::types::sql_types::Range

[+] Show declaration

pub struct Range<ST>(_);

[−] Expand description

The Range SQL type.

This wraps another type to represent a SQL range of that type.

ToSql impls

• (Bound<T>, Bound<T>) for any T which implements ToSql<ST>.

FromSql impls

• (Bound<T>, Bound<T>) for any T which implements FromSql<ST>.

Trait Implementations

impl<T, ST> Queryable<Range<ST>, Pg> for (Bound<T>, Bound<T>) where     T: FromSql<ST, Pg> + Queryable<ST, Pg>,

[+]

type Row = Self

The Rust type you'd like to map from.

fn build(row: Self) -> Self

[−]

Construct an instance of this type

impl<ST, T> AsExpression<Range<ST>> for (Bound<T>, Bound<T>)

[+]

type Expression = SqlBound<Range<ST>, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

[−]

Perform the conversion

impl<'a, ST, T> AsExpression<Range<ST>> for &'a (Bound<T>, Bound<T>)

[+]

type Expression = SqlBound<Range<ST>, Self>

The expression being returned

fn as_expression(self) -> Self::Expression

[−]

Perform the conversion

impl<T, ST> FromSqlRow<Range<ST>, Pg> for (Bound<T>, Bound<T>) where     (Bound<T>, Bound<T>): FromSql<Range<ST>, Pg>,

[+]

fn build_from_row<R: Row<Pg>>(row: &mut R) -> Result<Self>

[−]

See the trait documentation.

const FIELDS_NEEDED: usize

FIELDS_NEEDED: usize = 1

The number of fields that this type will consume. Must be equal to the number of times you would call row.take() in build_from_row

impl<T, ST> FromSql<Range<ST>, Pg> for (Bound<T>, Bound<T>) where     T: FromSql<ST, Pg>,

[+]

fn from_sql(bytes: Option<&[u8]>) -> Result<Self>

[−]

See the trait documentation.

impl<ST, T> ToSql<Range<ST>, Pg> for (Bound<T>, Bound<T>) where     T: ToSql<ST, Pg>,

[+]

fn to_sql<W: Write>(&self, out: &mut Output<W, Pg>) -> Result

[−]

See the trait documentation.

impl<ST: QueryId> QueryId for Range<ST>

[+]

type QueryId = Range<<ST as QueryId>::QueryId>

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = <ST as QueryId>::HAS_STATIC_QUERY_ID && true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

[−]

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl<ST> NotNull for Range<ST>

impl<ST> SingleValue for Range<ST>

impl<ST: Debug> Debug for Range<ST>

[+]

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

[−]

Formats the value using the given formatter.

impl<ST: Clone> Clone for Range<ST>

[+]

fn clone(&self) -> Range<ST>

[−]

Returns a copy of the value.

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

[−]

Performs copy-assignment from source.

impl<ST: Copy> Copy for Range<ST>

impl<ST: Default> Default for Range<ST>

[+]

fn default() -> Range<ST>

[−]

Returns the "default value" for a type.
