Required Methods§

Source

fn name(&self) -> &'static str

Returns the dialect name (e.g. “sqlite”, “postgres”, “mysql”).

Source

fn quote_identifier(&self, ident: &str) -> String

  • Postgres/SQLite: "identifier"
  • MySQL: `identifier`
Source

fn bind_parameter(&self, index: usize) -> String

Return the bind parameter placeholder for the given 1-based index.

  • Postgres: $1, $2, …
  • SQLite/MySQL: ?
Source

In older versions of Rust, dyn compatibility was called "object safety".
