Methods

Equals(object?)

Determines whether the specified obj is an Option<T>, and if so is equal to the current instance.

Declaration

[Pure]
public override bool Equals(object? obj)

Parameters

obj

object

An object to compare with this instance.

Returns

bool

true if the specified obj is an Option<T>, and is equal to this instance; otherwise, false.

Overrides

ValueType.Equals(object)

Remarks

Equality is determined with the following logic:

• if obj is an Option<T>, then use Equals(in Option<T>)
• if obj is a T, then use Equals(T?)
• true if obj is null, and this option does not have a value
• otherwise; false

T equality is determined via Default.

Equals(in Option<T>)

Determines whether the specified Option<T> other is equal to the current instance of Option<T>.

Declaration

[Pure]
public bool Equals(in Option<T> other)

Parameters

other

Option<T>

The other Option<T> to compare with this instance.

Returns

bool

true if the specified other is equal to this instance; otherwise, false.

Remarks

Equality is determined with the following logic:

• true if both are None()
• true if both are Some(T) and their T values are equal
• otherwise; false

T equality is determined via Default.

Equals(in Option<T>?)

Determines whether the specified Option<T> other is equal to the current instance of Option<T>.

Declaration

[Pure]
public bool Equals(in Option<T>? other)

Parameters

other

Option<T>?

The other Option<T> to compare with this instance.

Returns

bool

true if the specified other is equal to this instance; otherwise, false.

Remarks

Equality is determined with the following logic:

• true if both are None()
• true if one is None(), and the other is null
• true if both are Some(T) and their T values are equal
• otherwise; false

T equality is determined via Default.

Equals(T?)

Determines whether the specified T other is equal to the current instance of Option<T>.

Declaration

[Pure]
public bool Equals(T? other)

Parameters

other

T

The other T to compare with this instance.

Returns

bool

true if the specified other is equal to this instance; otherwise, false.

Remarks

Equality is determined with the following logic:

• true if this is None() and other is null
• true if this is Some(T) whose T values equals other
• otherwise; false

T equality is determined via Default.
