Error type for eoka.

#[non_exhaustive]: match with a _ => arm so new variants are additive.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Launch(String)

Failed to launch Chrome

Transport

Transport error

Fields

context: String

Description of what failed.

source: Option<Error>

Underlying IO error, if any.

Cdp

CDP protocol error. method/code carry command context when the error came from a command response, and are None for context-free failures.

Fields

method: Option<String>

CDP command method that failed, if known.

code: Option<i64>

CDP error code, if known.

message: String

Error message.

Navigation(String)

Navigation error

ElementNotFound(String)

Element not found in DOM

ElementNotVisible

Element exists in DOM but is not visible/rendered

Fields

selector: String

Selector that matched the hidden element.

Timeout(String)

Timeout

InputState(String)

Input action could not be completed because its held-input state was invalid.

ValueMismatch

A form control did not contain the requested value after filling.

Fields

selector: String

Selector supplied to the fill operation.

expected: String

Value requested by the caller.

actual: String

Value read back from the DOM.

Serialization(Error)

Serialization error

Decode(String)

Decode error (e.g., base64)

Io(Error)

IO error

ChromeNotFound

Chrome not found

Patching

Binary patching error

Fields

operation: String

Patching operation that failed.

message: String

Error message.

RetryExhausted

Retry exhausted

Fields

attempts: u32

Number of attempts made before giving up.

last_error: String

The last error encountered.

Implementations

impl Error

pub fn transport(context: impl Into<String>) -> Error

Create a transport error with context

pub fn transport_io(context: impl Into<String>, source: Error) -> Error

Create a transport error with IO source

pub fn cdp( method: impl Into<String>, code: i64, message: impl Into<String>, ) -> Error

Create a CDP error with full command context.

pub fn cdp_msg(message: impl Into<String>) -> Error

Create a CDP error without command context.

pub fn patching( operation: impl Into<String>, message: impl Into<String>, ) -> Error

Create a patching error

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for ServerError

fn from(err: Error) -> Self

Converts to this type from the input type.
