only.Expand description
A bind collector used by backends which transmit bind parameters as an opaque blob of bytes.
For most backends, this is the concrete implementation of BindCollector
that should be used.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.metadata: Vec<DB::TypeMetadata>
The metadata associated with each bind parameter.
This vec is guaranteed to be the same length as binds
.
binds: Vec<Option<Vec<u8>>>
The serialized bytes for each bind parameter.
This vec is guaranteed to be the same length as metadata
.
