Struct SqlxFragment 

pub struct SqlxFragment<B> { /* private fields */ }

Trusted SQL plus ordered bind values for one SQLx backend.

Implementations

impl<B> SqlxFragment<B>

pub fn trusted(sql: impl Into<String>) -> Self

Builds a fragment from SQL owned by the application.

Callers must not pass user-supplied text here. Dynamic values belong in bind fragments built with Self::bind.

pub fn bind(value: impl Into<SqlxValue>) -> Self

Builds a bind fragment from a supported SQLx scalar value.

pub fn binds(&self) -> impl Iterator<Item = &SqlxValue>

Returns the ordered bind values.

pub fn push_fragment(&mut self, fragment: Self)

Appends another fragment to this one.

impl<B> SqlxFragment<B>

where B: GatekeepSqlxBackend,

pub fn to_sql(&self) -> String

Converts the fragment to SQL with this backend’s placeholder syntax.

pub fn push_to(&self, builder: &mut QueryBuilder<B::Database>)

Appends this fragment to a SQLx query builder.

impl SqlxFragment<PostgresBackend>

pub fn to_postgres_sql(&self) -> String

Converts the fragment to Postgres placeholders ($1, $2, …).

Trait Implementations

impl<B> Clone for SqlxFragment<B>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<B: Debug> Debug for SqlxFragment<B>

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

Formats the value using the given formatter.

impl<B> Default for SqlxFragment<B>

fn default() -> Self

Returns the “default value” for a type.

impl<B: Eq> Eq for SqlxFragment<B>

impl<B: PartialEq> PartialEq for SqlxFragment<B>

fn eq(&self, other: &SqlxFragment<B>) -> 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.
