`pop arr` Full Usage: `pop arr` Parameters: arr : `ResizeArray<'T>` Returns: `'T` Modifiers: inline Type parameters: 'T	arr : `ResizeArray<'T>` Returns: `'T`
`popOff arr` Full Usage: `popOff arr` Parameters: arr : `ResizeArray<'T>` Modifiers: inline Type parameters: 'T	arr : `ResizeArray<'T>`
`rev xs` Full Usage: `rev xs` Parameters: xs : `ResizeArray<'T>` - The input ResizeArr. Returns: `ResizeArray<'T>` The reversed ResizeArr. Type parameters: 'T	Returns a new ResizeArray with the elements in reverse order. xs : `ResizeArray<'T>` The input ResizeArr. Returns: `ResizeArray<'T>` The reversed ResizeArr.
`singleton x` Full Usage: `singleton x` Parameters: x : `'T` Returns: `ResizeArray<'T>` Modifiers: inline Type parameters: 'T	x : `'T` Returns: `ResizeArray<'T>`
`sortBy projection xs` Full Usage: `sortBy projection xs` Parameters: projection : `'T -> 'Key` - The function to transform ResizeArray elements into the type that is compared. xs : `ResizeArray<'T>` - The input ResizeArr. Returns: `ResizeArray<'T>` The sorted ResizeArr. Type parameters: 'T, 'Key (requires comparison)	Sorts the elements of a ResizeArray, using the given projection for the keys and returning a new ResizeArr. Elements are compared using Operators.compare. This means "Z" is before "a". This is different from Collections.Generic.List.Sort() where "a" is before "Z" using IComparable interface. This is NOT a stable sort, i.e. the original order of equal elements is not necessarily preserved. For a stable sort, consider using Seq.sort. projection : `'T -> 'Key` The function to transform ResizeArray elements into the type that is compared. xs : `ResizeArray<'T>` The input ResizeArr. Returns: `ResizeArray<'T>` The sorted ResizeArr.
`thisNext rarr` Full Usage: `thisNext rarr` Parameters: rarr : `ResizeArray<'T>` Returns: `('T * 'T) seq` Type parameters: 'T	Yields looped Seq from (first, second) up to (last, first). The resulting seq has the same element count as the input Rarr. rarr : `ResizeArray<'T>` Returns: `('T * 'T) seq`
`tryFindBack predicate resizeArray` Full Usage: `tryFindBack predicate resizeArray` Parameters: predicate : `'T -> bool` - The function to test the input elements. resizeArray : `ResizeArray<'T>` - The input ResizeArray. Returns: `'T option` The last element that satisfies the predicate, or `None`. Type parameters: 'T	Returns the last element for which the given function returns `true`. Return None if no such element exists. predicate : `'T -> bool` The function to test the input elements. resizeArray : `ResizeArray<'T>` The input ResizeArray. Returns: `'T option` The last element that satisfies the predicate, or `None`.
`tryFindIndex predicate xs` Full Usage: `tryFindIndex predicate xs` Parameters: predicate : `'T -> bool` - The function to test the input elements. xs : `ResizeArray<'T>` - The input ResizeArr. Returns: `int option` The index of the first element that satisfies the predicate, or `None`. Type parameters: 'T	Returns the index of the first element in the ResizeArray that satisfies the given predicate. predicate : `'T -> bool` The function to test the input elements. xs : `ResizeArray<'T>` The input ResizeArr. Returns: `int option` The index of the first element that satisfies the predicate, or `None`.
