Struct FieldState 

pub struct FieldState<T> { /* private fields */ }

Implementations

impl<T> FieldState<T>

pub const fn omitted() -> Self

pub fn typed(data_type: DataTypeDescriptor) -> Self

pub fn value(&self) -> &FieldValue<T>

pub fn is_dirty(&self) -> bool

pub fn is_omitted(&self) -> bool

pub fn set(&mut self, value: impl Into<T>)

pub fn set_null(&mut self)

pub fn set_null_as(&mut self, data_type: DataTypeDescriptor)

pub fn unset(&mut self)

Remove the field from the next INSERT/UPDATE. This also clears a pending dirty transition; it never writes SQL NULL implicitly.

pub fn hydrate(&mut self, value: FieldValue<T>)

pub fn mark_clean(&mut self)
