Enum pg_async::PgQueryPiece

pub enum PgQueryPiece {
    Static(&'static str),
    Plain(String),
    Literal(String),
    InlLiteral(InlinableString),
    Bytea(Vec<u8>),
}

A part of an SQL query text. The query is constructed by adding Plain pieces “as is” and escaping the Literal pieces.

For example, a properly escaped “SELECT ‘foo’” might be generated with

    use pg_async::PgQueryPiece::{Static as S, Literal as L};
    vec![S("SELECT "), L("foo".into)]

Variants

Static(&'static str)

Static strings are included in the query “as is”.

Plain(String)

Plain strings are included in the query “as is”.

Literal(String)

Literals are escaped with PQescapeLiteral (which also places them into the single quotes).

InlLiteral(InlinableString)

Literals are escaped with PQescapeLiteral (which also places them into the single quotes).

InlLiteral allows for small string optimization.

Bytea(Vec<u8>)

Binary data, escaped with PQescapeByteaConn. Single quotes aren’t added by the escape.
