Bit flags that indicate the type of buffer.

MSDN

• SecBuffer structure (BufferType parameter)

Variants

Empty = 0

Data = 1

The buffer contains common data. The security package can read and write this data, for example, to encrypt some or all of it.

Token = 2

The buffer contains the security token portion of the message. This is read-only for input parameters or read/write for output parameters.

TransportToPackageParameters = 3

Missing = 4

The security package uses this value to indicate the number of missing bytes in a particular message.

Extra = 5

The security package uses this value to indicate the number of extra or unprocessed bytes in a message.

StreamTrailer = 6

The buffer contains a protocol-specific trailer for a particular record. It is not usually of interest to callers.

StreamHeader = 7

The buffer contains a protocol-specific header for a particular record. It is not usually of interest to callers.

NegotiationInfo = 8

Padding = 9

Stream = 10

ObjectIdsList = 11

ObjectIdsListSignature = 12

Target = 13

This flag is reserved. Do not use it.

ChannelBindings = 14

The buffer contains channel binding information.

ChangePasswordResponse = 15

The buffer contains a DOMAIN_PASSWORD_INFORMATION structure.

TargetHost = 16

The buffer specifies the service principal name (SPN) of the target.

Alert = 17

The buffer contains an alert message.

ApplicationProtocol = 18

The buffer contains a list of application protocol IDs, one list per application protocol negotiation extension type to be enabled.

AttributeMark = 4_026_531_840

The buffer contains a bitmask for a ReadOnly buffer.

ReadOnly = 2_147_483_648

The buffer is read-only with no checksum. This flag is intended for sending header information to the security package for computing the checksum. The package can read this buffer, but cannot modify it.

ReadOnlyWithChecksum = 268_435_456

The buffer is read-only with a checksum.

Trait Implementations

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_isize(n: isize) -> Option<Self>

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i8(n: i8) -> Option<Self>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i16(n: i16) -> Option<Self>

Converts an i16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

Converts an i32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i128(n: i128) -> Option<Self>

Converts an i128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_u128(n: u128) -> Option<Self>

Converts an u128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f32(n: f32) -> Option<Self>

Converts a f32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_f64(n: f64) -> Option<Self>

Converts a f64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

impl PartialEq for SecurityBufferType

fn eq(&self, other: &SecurityBufferType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToPrimitive for SecurityBufferType

fn to_i64(&self) -> Option<i64>

Converts the value of self to an i64. If the value cannot be represented by an i64, then None is returned.

fn to_u64(&self) -> Option<u64>

Converts the value of self to a u64. If the value cannot be represented by a u64, then None is returned.

fn to_isize(&self) -> Option<isize>

Converts the value of self to an isize. If the value cannot be represented by an isize, then None is returned.

fn to_i8(&self) -> Option<i8>

Converts the value of self to an i8. If the value cannot be represented by an i8, then None is returned.
