Trait odbc_api::parameter::InputParameter [−][src]
pub unsafe trait InputParameter: HasDataType + CData { }Expand description
Use implementations of this type as arguments to SQL Statements.
Safety
Considerations for implementers
Extend the crate::handles::HasDataType trait with the guarantee, that the bound parameter
buffer contains at least one element.
Since the indicator provided by implementation is used to indicate the length of the value in the buffer, care must be taken to prevent out of bounds access in case the implementation also is used as an output parameter, and contains truncated values (i.e. the indicator is longer than the buffer and the value within).
