Trait Implementations

impl CqlParser for NomParser

fn parse<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlStatement>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a complete CQL statement from input text.

fn parse_type<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlDataType>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a CQL data type specification (e.g., list<text>, map<uuid, bigint>).

fn parse_expression<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlExpression>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a CQL expression (e.g., id = ? AND name LIKE 'test%').

fn parse_identifier<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlIdentifier>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a CQL identifier (table name, column name, etc.).

fn parse_literal<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlLiteral>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a literal value (e.g., 'hello', 42, true).

fn parse_column_definitions<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<CqlColumnDef>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse a list of column definitions (for CREATE TABLE).

fn parse_table_options<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<CqlTableOptions>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parse CREATE TABLE options (e.g., WITH comment = 'test').

fn validate_syntax(&self, input: &str) -> bool

Lightweight check that input appears to be valid CQL syntax.

fn backend_info(&self) -> ParserBackendInfo

Get parser backend information.

impl Debug for NomParser

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

Formats the value using the given formatter.
