Implementations
sourceimpl PgTypeMetadata
impl PgTypeMetadata
sourcepub fn new(type_oid: u32, array_oid: u32) -> Self
pub fn new(type_oid: u32, array_oid: u32) -> Self
Create a new instance of this type based on known constant OIDs.
Please refer to PgMetadataLookup for a way to query OIDs of custom types at run time
sourcepub fn from_result(r: Result<(u32, u32), FailedToLookupTypeError>) -> Self
Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes
only.
pub fn from_result(r: Result<(u32, u32), FailedToLookupTypeError>) -> Self
i-implement-a-third-party-backend-and-opt-into-breaking-changes
only.Create a new instance of this type based on dynamically lookup informations
This function is usfull for third party crates that may implement a custom postgres connection type and want to bring their own lookup mechanism.
Otherwise refer to PgMetadataLookup for a way to automatically implement the corresponding lookup functionality
