Struct Column 

pub struct Column {
    pub name: Option<String>,
    pub ty_str: String,
    pub ty_params: Vec<Box<Expr>>,
    pub default: Option<Box<Expr>>,
    pub notnull_conflict_clause: Option<ResolveType>,

}

Fields

name: Option<String>

ty_str: String

ty_params: Vec<Box<Expr>>

default: Option<Box<Expr>>

notnull_conflict_clause: Option<ResolveType>

ON CONFLICT clause for NOT NULL constraint on this column.

Implementations

impl Column

pub fn affinity(&self) -> Affinity

pub fn set_base_affinity(&mut self, affinity: Affinity)

Set the base type affinity override for a custom type column. This ensures affinity rules use the custom type’s BASE type rather than applying SQLite name-based rules to the type name.

pub fn affinity_with_strict(&self, is_strict: bool) -> Affinity

pub fn new_default_text( name: Option<String>, ty_str: String, default: Option<Box<Expr>>, ) -> Self

pub fn new_default_integer( name: Option<String>, ty_str: String, default: Option<Box<Expr>>, ) -> Self

pub fn new( name: Option<String>, ty_str: String, default: Option<Box<Expr>>, generated: Option<Box<Expr>>, ty: Type, col: Option<CollationSeq>, coldef: ColDef, ) -> Self

pub const fn ty(&self) -> Type

pub const fn set_ty(&mut self, ty: Type)

pub const fn collation_opt(&self) -> Option<CollationSeq>

pub const fn collation(&self) -> CollationSeq

pub const fn has_explicit_collation(&self) -> bool

pub const fn set_collation(&mut self, c: Option<CollationSeq>)

pub fn primary_key(&self) -> bool

pub const fn is_rowid_alias(&self) -> bool

pub const fn notnull(&self) -> bool

pub const fn explicit_notnull(&self) -> bool

pub const fn unique(&self) -> bool

pub const fn hidden(&self) -> bool

pub fn ensure_not_generated( &self, verb_phrase: &str, col_name: &str, ) -> Result<()>

Returns an error if this column is a generated column. verb_phrase should describe the operation, e.g. “INSERT into” or “UPDATE”.

pub fn generated_type(&self) -> &GeneratedType

pub const fn is_generated(&self) -> bool

pub const fn is_virtual_generated(&self) -> bool

pub fn generated_expr(&self) -> Option<&Expr>

pub fn generated_expr_mut(&mut self) -> Option<&mut Expr>

pub fn set_generated_original_sql(&mut self, new_sql: String)

pub const fn set_primary_key(&mut self, v: bool)

pub const fn set_rowid_alias(&mut self, v: bool)

pub const fn set_notnull(&mut self, v: bool)

pub const fn set_unique(&mut self, v: bool)

pub const fn set_hidden(&mut self, v: bool)

pub const fn is_array(&self) -> bool

pub const fn array_dimensions(&self) -> u32

Number of array dimensions (0 = scalar, 1 = [], 2 = [][], etc.)

pub fn set_array_dimensions(&mut self, dims: u32)
