Struct Postgres 

pub struct Postgres;

PostgreSQL dialect marker.

Trait Implementations

impl Clone for Postgres

fn clone(&self) -> Postgres

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Postgres

impl Debug for Postgres

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

Formats the value using the given formatter.

impl Dialect for Postgres

fn quote_char() -> char

The identifier quote character (e.g. backtick for MySQL, " for ANSI).

fn write_placeholder(out: &mut String, n: usize)

Write the bind placeholder for the n-th parameter (1-based) into out.

fn supports_returning() -> bool

Whether this dialect supports the RETURNING clause.

fn supports_distinct_on() -> bool

Whether this dialect supports SELECT DISTINCT ON (cols). Defaults to false; only Postgres overrides to true. Compiling a distinct_on query against a dialect that returns false panics.

fn ilike_is_native() -> bool

Whether this dialect has a native case-insensitive ILIKE operator. Defaults to false; only Postgres overrides to true. When false, where_ilike is compiled as LOWER(col) LIKE LOWER(?).

fn upsert_style() -> UpsertStyle

How this dialect expresses an upsert. Defaults to UpsertStyle::OnConflict (Postgres / SQLite); MySQL overrides to UpsertStyle::OnDuplicateKey.

fn supports_row_locking() -> bool

Whether this dialect supports row-locking clauses (FOR UPDATE / FOR SHARE, optionally SKIP LOCKED / NOWAIT). Defaults to true (Postgres / MySQL); SQLite overrides to false, where such clauses are a silent no-op (SQLite locks the whole database, not rows).

impl Eq for Postgres

impl PartialEq for Postgres

fn eq(&self, other: &Postgres) -> 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 SqlxDialect for Postgres

Available on crate feature sqlx_postgres only.

type Database = Postgres

The sqlx Database this dialect binds against.

fn bind_arguments(binds: &[Value]) -> PgArguments

Build owned Arguments for binds.
