Struct SessionError 

pub struct SessionError {
    pub message: String,
    pub kind: SessionErrorKind,
    pub stdout: Option<String>,
    pub parts: Vec<(Verbosity, String)>,
    pub annotation: Option<String>,
    pub preface: Box<[String]>,
}

Fields

message: String

kind: SessionErrorKind

stdout: Option<String>

A line Composer writes on STDOUT next to the error ($io->write after $io->writeError), as UpdateCommand does for a temporary constraint that misses the root’s.

parts: Vec<(Verbosity, String)>

The message as Composer writes it, piece by piece with each piece’s level (IOInterface::QUIET for the headline of an unsolvable set and the --no-dev warning, the default level for the problems). Empty when the whole message has one level, the caller’s.

annotation: Option<String>

What Composer hands to GithubActionError::emit for this error, when it is not the message itself: the headline and the problems of an unsolvable set ($err."\n".$prettyProblem), without the --no-dev warning or the dev extraction’s two hint lines.

preface: Box<[String]>

Lines Composer has written before it throws, which the error must not lose: the warnings a degraded repository held while the list filter of install’s verification ran (ComposerRepository writes them as it loads, before the exception of another fetch).

Implementations

impl SessionError

pub fn new(message: impl Into<String>) -> Self

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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<FilterError> for SessionError

A filter error, on the other hand, can be either.

fn from(e: FilterError) -> SessionError

Converts to this type from the input type.

impl From<LoadError> for SessionError

fn from(e: LoadError) -> SessionError

Converts to this type from the input type.

impl From<PlatformError> for SessionError

fn from(e: PlatformError) -> SessionError

Converts to this type from the input type.

impl From<PolicyError> for SessionError

fn from(e: PolicyError) -> SessionError

Converts to this type from the input type.

impl From<PoolError> for SessionError

fn from(e: PoolError) -> SessionError

Converts to this type from the input type.

impl From<RepoError> for SessionError

A repository error keeps its nature: Composer rewrites a TransportException’s code to Installer::ERROR_TRANSPORT_EXCEPTION (100) before Symfony turns it into an exit code, so a failure to FETCH something does not exit like a failure to understand it.

fn from(e: RepoError) -> SessionError

Converts to this type from the input type.

impl From<RootError> for SessionError

fn from(e: RootError) -> SessionError

Converts to this type from the input type.
