pub struct PostgresRenderer { /* private fields */ }

Implementations

impl PostgresRenderer

pub fn new() -> Self

pub fn with_param_style(self, style: ParamStyle) -> Self

Use %s placeholders (psycopg / DB-API 2.0) instead of $1.

pub fn render_schema_stmt( &self, stmt: &SchemaMutationStmt, ) -> RenderResult<(String, Vec<Value>)>

Convenience: render a DDL statement to SQL string + params.

pub fn render_transaction_stmt( &self, stmt: &TransactionStmt, ) -> RenderResult<(String, Vec<Value>)>

Convenience: render a TCL statement to SQL string + params.

pub fn render_mutation_stmt( &self, stmt: &MutationStmt, ) -> RenderResult<(String, Vec<Value>)>

Convenience: render a DML statement to SQL string + params.

pub fn render_query_stmt( &self, stmt: &QueryStmt, ) -> RenderResult<(String, Vec<Value>)>

Convenience: render a SELECT query to SQL string + params.
