Implementations

impl<T: SqlStruct> Struct<T>

pub fn new() -> Self

pub fn with_field_mapper(&self, mapper: FieldMapperFunc) -> Self

WithFieldMapper: return a shadow copy with a different mapper.

• Passing identity_mapper() matches the effect of a nil mapper.

pub fn for_flavor(&self, flavor: Flavor) -> Self

ForFlavor: return a shadow copy with a different flavor.

pub fn with_tag(&self, tags: impl IntoIterator<Item = &'static str>) -> Self

WithTag: return a shadow copy with additional tags.

pub fn without_tag(&self, tags: impl IntoIterator<Item = &'static str>) -> Self

WithoutTag: return a shadow copy excluding specific tags.

pub fn columns(&self) -> Vec<String>

Columns: return unquoted column names for write.

pub fn columns_for_tag(&self, tag: &str) -> Option<Vec<String>>

ColumnsForTag: return columns for a specific tag; None if tag not defined.

pub fn values(&self, v: &T) -> Vec<Arg>

Values: return values for write in the same order as columns().

pub fn values_for_tag(&self, tag: &str, v: &T) -> Option<Vec<Arg>>

ValuesForTag: values restricted to a tag; None if tag not defined.

pub fn foreach_read(&self, trans: impl FnMut(&str, bool, &FieldMeta))

ForeachRead: iterate readable fields.

• dbtag: db tag (may be empty)
• is_quoted: whether the column needs quoting
• field_meta: Rust-side metadata instead of reflect.StructField

pub fn foreach_write(&self, trans: impl FnMut(&str, bool, &FieldMeta))

ForeachWrite: iterate writable fields.

pub fn addr<'a>(&self, st: &'a mut T) -> Vec<ScanCell<'a>>

Addr: return scan targets for readable fields.

pub fn addr_for_tag<'a>( &self, tag: &str, st: &'a mut T, ) -> Option<Vec<ScanCell<'a>>>

AddrForTag: scan targets filtered by tag; None if tag not defined.

pub fn addr_with_cols<'a>( &self, cols: &[&str], st: &'a mut T, ) -> Option<Vec<ScanCell<'a>>>

AddrWithCols: scan targets for specific columns; None if any column is missing.

pub fn select_from(&self, table: &str) -> SelectBuilder

pub fn select_from_for_tag(&self, table: &str, tag: &str) -> SelectBuilder

SelectFromForTag: build SELECT for a tag (deprecated).

pub fn update(&self, table: &str, value: &T) -> UpdateBuilder

pub fn update_for_tag(&self, table: &str, tag: &str, value: &T) -> UpdateBuilder

UpdateForTag: build UPDATE for a tag (deprecated).

pub fn delete_from(&self, table: &str) -> DeleteBuilder

pub fn insert_into<'a>( &self, table: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,

pub fn insert_into_for_tag<'a>( &self, table: &str, tag: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,

InsertIntoForTag: build INSERT for a tag (deprecated).

pub fn insert_ignore_into_for_tag<'a>( &self, table: &str, tag: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,

pub fn replace_into_for_tag<'a>( &self, table: &str, tag: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,

pub fn insert_into_any<'a>( &self, table: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

InsertIntoAny: ignore values that are not of type T (like Go’s permissive interface slice).

pub fn insert_ignore_into_any<'a>( &self, table: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

pub fn replace_into_any<'a>( &self, table: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

pub fn insert_into_for_tag_any<'a>( &self, table: &str, tag: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

pub fn insert_ignore_into_for_tag_any<'a>( &self, table: &str, tag: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

pub fn replace_into_for_tag_any<'a>( &self, table: &str, tag: &str, values: impl IntoIterator<Item = &'a dyn Any>, ) -> InsertBuilder

where T: 'static,

pub fn insert_ignore_into<'a>( &self, table: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,

pub fn replace_into<'a>( &self, table: &str, rows: impl IntoIterator<Item = &'a T>, ) -> InsertBuilder

where T: 'a,
