Enum CustomActionResult 

#[repr(u32)]
pub enum CustomActionResult {
    Success = 0,
    Skip = 259,
    Cancel = 1_602,
    Failure = 1_603,
    NotExecuted = 1_626,
}

A result to return from a custom action.

This allows you to use the ? operator to map any Result<T, E> to CustomActionResult::Failure.

Example

use std::ffi::OsString;
use msica::prelude::*;

#[no_mangle]
pub extern "C" fn MyCustomAction(session: Session) -> CustomActionResult {
    let productName = session.property("ProductName")?;

    // Do something with `productName`.

    Success
}

Variants

Success = 0

Completed actions successfully.

Skip = 259

Skip remaining actions. Not an error.

Cancel = 1_602

User terminated prematurely.

Failure = 1_603

Unrecoverable error occurred.

NotExecuted = 1_626

Action not executed.

Trait Implementations

impl Clone for CustomActionResult

fn clone(&self) -> CustomActionResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomActionResult

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

Formats the value using the given formatter.

impl Display for CustomActionResult

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

Formats the value using the given formatter.

impl From<CustomActionResult> for NonZeroU32

fn from(value: CustomActionResult) -> Self

Converts to this type from the input type.

impl From<CustomActionResult> for u32

fn from(value: CustomActionResult) -> Self

Converts to this type from the input type.

impl From<u32> for CustomActionResult

fn from(code: u32) -> Self

Converts to this type from the input type.

impl<E: Error> FromResidual<Result<Infallible, E>> for CustomActionResult

default fn from_residual(_: Result<Infallible, E>) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2)

Constructs the type from a compatible Residual type.

impl FromResidual<Result<Infallible, Error>> for CustomActionResult

fn from_residual(residual: Result<Infallible, Error>) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2)

Constructs the type from a compatible Residual type.

impl FromResidual for CustomActionResult

fn from_residual(residual: <CustomActionResult as Try>::Residual) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2)

Constructs the type from a compatible Residual type.

impl PartialEq for CustomActionResult

fn eq(&self, other: &CustomActionResult) -> 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.

impl Try for CustomActionResult

type Output = u32

🔬This is a nightly-only experimental API. (try_trait_v2)

The type of the value produced by ? when not short-circuiting.

type Residual = NonZero<u32>

🔬This is a nightly-only experimental API. (try_trait_v2)

The type of the value passed to FromResidual::from_residual as part of ? when short-circuiting.

fn branch(self) -> ControlFlow<Self::Residual, Self::Output>

🔬This is a nightly-only experimental API. (try_trait_v2)

Used in ? to decide whether the operator should produce a value (because this returned ControlFlow::Continue) or propagate a value back to the caller (because this returned ControlFlow::Break).

fn from_output(_: Self::Output) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2)

Constructs the type from its Output type.
