extension [T <: AnyRef](arr: Array[T])
def binarySearch(x: T | Null): Int
extension (it: Iterator[Symbol])
final def findSymbol(p: Symbol => Boolean): Symbol

Implements a findSymbol method on iterators of Symbols that works like find but avoids Option, replacing None with NoSymbol.

Attributes

extension (names: List[String])
def containsPhase(phase: Phase): Boolean

Test whether a list of strings representing phases contains a given phase. See config.CompilerCommand#explainAdvanced for the exact meaning of "contains" here.

Attributes

extension (s: String)
def concat(name: Name)(using Context): SimpleName
def indented(width: Int): String
def sliceToTermName(start: Int, end: Int)(using Context): SimpleName

Create a term name from a string slice, using a common buffer. This avoids some allocation relative to termName(s)

extension (sc: StringContext)
def em(args: Shown*)(using Context): String

Formatting for error messages: Like i but suppress follow-on error messages after the first one if some of their arguments are "non-sensical".

Attributes

def ex(args: Shown*)(using Context): String

Formatting with added explanations: Like em, but add explanations to give more info about type variables and to disambiguate where needed.
