Struct gio::Credentials

source ·
pub struct Credentials { /* private fields */ }
Expand description

The Credentials type is a reference-counted wrapper for native credentials. This information is typically used for identifying, authenticating and authorizing other processes.

Some operating systems supports looking up the credentials of the remote peer of a communication endpoint - see e.g. SocketExt::credentials().

Some operating systems supports securely sending and receiving credentials over a Unix Domain Socket, see UnixCredentialsMessage, g_unix_connection_send_credentials() and g_unix_connection_receive_credentials() for details.

On Linux, the native credential type is a struct ucred - see the unix(7) man page for details. This corresponds to CredentialsType::LinuxUcred.

On Apple operating systems (including iOS, tvOS, and macOS), the native credential type is a struct xucred. This corresponds to CredentialsType::AppleXucred.

On FreeBSD, Debian GNU/kFreeBSD, and GNU/Hurd, the native credential type is a struct cmsgcred. This corresponds to CredentialsType::FreebsdCmsgcred.

On NetBSD, the native credential type is a struct unpcbid. This corresponds to CredentialsType::NetbsdUnpcbid.

On OpenBSD, the native credential type is a struct sockpeercred. This corresponds to CredentialsType::OpenbsdSockpeercred.

On Solaris (including OpenSolaris and its derivatives), the native credential type is a ucred_t. This corresponds to CredentialsType::SolarisUcred.

Since GLib 2.72, on Windows, the native credentials may contain the PID of a process. This corresponds to CredentialsType::Win32Pid.

Implementations§

source§

impl Credentials

source

pub fn new() -> Credentials

Creates a new Credentials object with credentials matching the the current process.

Returns

A Credentials. Free with g_object_unref().

source

pub fn unix_pid(&self) -> Result<i32, Error>

Available on Unix only.

Tries to get the UNIX process identifier from self. This method is only available on UNIX platforms.

This operation can fail if Credentials is not supported on the OS or if the native credentials type does not contain information about the UNIX process ID.

Returns

The UNIX process ID, or -1 if error is set.

source

pub fn unix_user(&self) -> Result<u32, Error>

Available on Unix only.

Tries to get the UNIX user identifier from self. This method is only available on UNIX platforms.

This operation can fail if Credentials is not supported on the OS or if the native credentials type does not contain information about the UNIX user.

Returns

The UNIX user identifier or -1 if error is set.

source

pub fn is_same_user(&self, other_credentials: &Credentials) -> Result<(), Error>

Checks if self and other_credentials is the same user.

This operation can fail if Credentials is not supported on the the OS.

other_credentials

A Credentials.

Returns

true if self and other_credentials has the same user, false otherwise or if error is set.

source

pub fn set_unix_user(&self, uid: u32) -> Result<(), Error>

Available on Unix only.

Tries to set the UNIX user identifier on self. This method is only available on UNIX platforms.

This operation can fail if Credentials is not supported on the OS or if the native credentials type does not contain information about the UNIX user. It can also fail if the OS does not allow the use of “spoofed” credentials.

uid

The UNIX user identifier to set.

Returns

true if uid was set, false if error is set.

source

pub fn to_str(&self) -> GString

Creates a human-readable textual representation of self that can be used in logging and debug messages. The format of the returned string may change in future GLib release.

Returns

A string that should be freed with g_free().
