Struct getrandom::Error

source · [−]

pub struct Error(_);

Expand description

A small and no_std compatible error type

+

The Error::raw_os_error() will indicate if the error is from the OS, and +if so, which error code the OS gave the application. If such an error is +encountered, please consult with your system documentation.

+

Internally this type is a NonZeroU32, with certain values reserved for +certain purposes, see Error::INTERNAL_START and Error::CUSTOM_START.

+

If this crate’s "std" Cargo feature is enabled, then:

+

getrandom::Error implements +std::error::Error
std::io::Error implements +From<getrandom::Error>.

+

Implementations

impl Error

pub const UNSUPPORTED: Error = _

This target/platform is not supported by getrandom.

+

pub const ERRNO_NOT_POSITIVE: Error = _

The platform-specific errno returned a non-positive value.

+

pub const IOS_SEC_RANDOM: Error = _

Call to iOS SecRandomCopyBytes failed.

+

pub const WINDOWS_RTL_GEN_RANDOM: Error = _

Call to Windows RtlGenRandom failed.

+

pub const FAILED_RDRAND: Error = _

RDRAND instruction failed due to a hardware issue.

+

pub const NO_RDRAND: Error = _

RDRAND instruction unsupported on this target.

+

pub const WEB_CRYPTO: Error = _

The environment does not support the Web Crypto API.

+

pub const WEB_GET_RANDOM_VALUES: Error = _

Calling Web Crypto API crypto.getRandomValues failed.

+

pub const VXWORKS_RAND_SECURE: Error = _

On VxWorks, call to randSecure failed (random number generator is not yet initialized).

+

pub const NODE_CRYPTO: Error = _

Node.js does not have the crypto CommonJS module.

+

pub const NODE_RANDOM_FILL_SYNC: Error = _

Calling Node.js function crypto.randomFillSync failed.

+

pub const NODE_ES_MODULE: Error = _

Called from an ES module on Node.js. This is unsupported, see: +https://docs.rs/getrandom#nodejs-es-module-support.

+

pub const INTERNAL_START: u32 = 2_147_483_648u32

Codes below this point represent OS Errors (i.e. positive i32 values). +Codes at or above this point, but below Error::CUSTOM_START are +reserved for use by the rand and getrandom crates.

+

pub const CUSTOM_START: u32 = 3_221_225_472u32

Codes at or above this point can be used by users to define their own +custom errors.

+

pub fn raw_os_error(self) -> Option<i32>

Extract the raw OS error code (if this error came from the OS)

+

This method is identical to std::io::Error::raw_os_error(), except +that it works in no_std contexts. If this method returns None, the +error value can still be formatted via the Display implementation.

+

pub const fn code(self) -> NonZeroU32

Extract the bare error code.

+

This code can either come from the underlying OS, or be a custom error. +Use Error::raw_os_error() to disambiguate.

+
