Errors returned while reading or applying IniSettingsRetention.

Variants

RetentionUnderflowsSessionDate

The requested period would underflow Dear ImGui’s packed date year.

Fields

session_date: IniSessionDate

Date used as the retention upper bound.

months: NonZeroU16

Requested automatic-discard period.

max_months: u16

Largest supported period for session_date.

LockedAfterFirstFrame

The session date is immutable after Dear ImGui has started its first frame.

LockedAfterSettingsLoad

Automatic cleanup cannot be changed after settings have already been loaded.

InvalidNativeSessionDate

Native platform state contains a date outside the safe packed range.

Fields

raw: i32

InvalidNativeAutoDiscardMonths

Native IO state contains an unsupported automatic-discard period.

Fields

raw: i32

InvalidNativeState

Native settings fields encode a combination that cannot be represented safely.

Fields

reason: &'static str

Explanation of the inconsistent native fields.

👎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
