Instance Method Detail

def [](key : ASTNode) : ASTNode #

Similar to Hash#[]


View source
def []=(key : ASTNode) : ASTNode #

Similar to Hash#[]=


View source
def double_splat(trailing_string : StringLiteral = nil) : MacroId #

Returns a MacroId with all of this hash elements joined by commas.

If trailing_string is given, it will be appended to the result unless this hash is empty. This lets you splat a hash and optionally write a trailing comma if needed.


View source
def empty? : BoolLiteral #

Similar to Hash#empty?


View source
def keys : ArrayLiteral #

Similar to Hash#keys


View source
def map : ArrayLiteral #

Similar to Hash#map


View source
def of_key : ASTNode | Nop #

Returns the type specified at the end of the Hash literal, if any.

This refers to the key type after brackets in {} of String => Int32.


View source
def of_value : ASTNode | Nop #

Returns the type specified at the end of the Hash literal, if any.

This refers to the value type after brackets in {} of String => Int32.


View source
def size : NumberLiteral #

Similar to Hash#size


View source
def to_a : Crystal::Macros::ArrayLiteral(TupleLiteral) #

Similar to Hash#to_a


View source
def type : Path | Nop #

Returns the type that receives the items of the array.

This refers to the part before brackets in MyHash{'a' => 1, 'b' => 2}


View source
def values : ArrayLiteral #

Similar to Hash#values
