dpiEncodingInfo

Struct dpiEncodingInfo 

Source
#[repr(C)]
pub struct dpiEncodingInfo { pub encoding: *const c_char, pub maxBytesPerCharacter: i32, pub nencoding: *const c_char, pub nmaxBytesPerCharacter: i32, }
Expand description

This structure is used for transferring encoding information from ODPI-C. All of the information here remains valid as long as a reference is held to the standalone connection (by calling dpiConn_getEncodingInfo()) or session pool (by calling dpiPool_getEncodingInfo()) from which the information was taken.

Fields§

§encoding: *const c_char

The encoding used for CHAR data, as a null-terminated ASCII string.

§maxBytesPerCharacter: i32

The maximum number of bytes required for each character in the encoding used for CHAR data. This value is used when calculating the size of buffers required when lengths in characters are provided.

§nencoding: *const c_char

The encoding used for NCHAR data, as a null-terminated ASCII string.

§nmaxBytesPerCharacter: i32

The maximum number of bytes required for each character in the encoding used for NCHAR data. Since this information is not directly available from Oracle it is only accurate if the encodings used for CHAR and NCHAR data are identical or one of ASCII or UTF-8; otherwise a value of 4 is assumed. This value is used when calculating the size of buffers required when lengths in characters are provided.
