Enum - Error

Authoritative source: ref/doc/iced/enum.Error.html.

# Rustdoc summary

An error that occurred while running an application.

# Verified declaration

rust
pub enum Error {
    ExecutorCreationFailed(Error),
    WindowCreationFailed(Box<dyn Error + Send + Sync>),
    GraphicsCreationFailed(Error),
}

# When to use

Use this enum when modeling or configuring the set of discrete variants represented by iced::....

# Why to use

It provides explicit, typed variant semantics that match runtime and widget APIs documented in rustdoc.

# Example References

# Use this when...

  • You need a typed set of variants for layout/style/runtime behavior.
  • You want pattern matching instead of ad-hoc booleans.
  • You are configuring widget behavior with explicit choices.

# Minimal example

rust
// Choose an enum variant and pass it into widget/runtime configuration.

# How it works

Enums model constrained strategy choices in Iced APIs. They keep configuration readable and make invalid combinations easier to catch at compile time.

# Common patterns

rust
// Use match expressions for app-driven variant selection.

# Gotchas / tips

  • Similar variant names may have different effects across APIs.
  • Keep variant selection close to widget config for clarity.
  • Confirm semantics in rustdoc for edge cases.
