ColumnDeclaration

Struct ColumnDeclaration 

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

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§

Source§

impl ColumnDeclaration

Source

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.

Source

pub fn vtab_declaration(&self) -> String

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