Enum HeadlessError 

pub enum HeadlessError {
    TimedOut {
        timeout_ms: u128,
    },
    PermissionDenied {
        origin: Origin,
        policy: NetworkPolicy,
    },
    SandboxRequired,
    SnapshotFailed(String),
}

Headless fallback errors.

Variants

TimedOut

Rendering exceeded the configured timeout.

Fields

timeout_ms: u128

Timeout in milliseconds.

PermissionDenied

A requested origin was denied by policy.

Fields

origin: Origin

Denied origin.

policy: NetworkPolicy

Policy that denied the request.

SandboxRequired

Sandbox policy was not strong enough.

SnapshotFailed(String)

The backend could not produce a snapshot.

Trait Implementations

impl Clone for HeadlessError

fn clone(&self) -> HeadlessError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeadlessError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for HeadlessError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for HeadlessError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for HeadlessError

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

Tests for self and other values to be equal, and is used by ==.

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

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