Enum CastMode 

pub enum CastMode {
    Normal,
    Try,
}

Whether the cast is called as a regular CAST or a TRY_CAST.

In Try mode, conversion failures should write NULL for the failed row and call CastFunctionInfo::set_row_error rather than aborting the whole query.

Variants

Normal

Regular CAST — any failure aborts the query.

Try

TRY_CAST — failures produce NULL; use per-row error reporting.

Trait Implementations

impl Clone for CastMode

fn clone(&self) -> CastMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CastMode

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

Formats the value using the given formatter.

impl PartialEq for CastMode

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

Tests for self and other values to be equal, and is used by ==.

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

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