[−][src]Struct msql_srv::Value
MySQL value as provided when executing prepared statements.
Implementations
impl<'a> Value<'a>
[src]
pub fn into_inner(self) -> ValueInner<'a>
[src]
Return the inner stored representation of this value.
This may be useful for when you do not care about the exact data type used for a column,
but instead wish to introspect a value you are given at runtime. Note that the contained
value may be stored in a type that is more general than what the corresponding parameter
type allows (e.g., a u8
will be stored as an u64
).
pub fn is_null(&self) -> bool
[src]
Returns true if this is a NULL value
