Struct sqlite_loadable::vtab_argparse::ColumnDeclaration

pub struct ColumnDeclaration {
    pub name: String,
    pub declared_type: Option<String>,
    pub constraints: Option<String>,
}

A column declaration that defines a single column. Example: "name text" would parse to a column with the name "name" and declared type of "text".

Fields

name: String

Name of declared column

declared_type: Option<String>

constraints: Option<String>

Implementations

impl ColumnDeclaration

pub fn affinity(&self) -> ColumnAffinity

Determines the column declaration’s “affinity”, based on the parsed declared type. Uses the same rules as https://www.sqlite.org/datatype3.html#determination_of_column_affinity.

pub fn vtab_declaration(&self) -> String

Formats the column declaration into a way that a CREATE TABLE statement expects (“escaping” the column name).

Trait Implementations

impl Clone for ColumnDeclaration

fn clone(&self) -> ColumnDeclaration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnDeclaration

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

Formats the value using the given formatter.

impl PartialEq<ColumnDeclaration> for ColumnDeclaration

fn eq(&self, other: &ColumnDeclaration) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
