Instance Method Summary

• #==(other : self)
• #absolute_path : String | Nil

  Returns:

• #column : Int32 | Nil

  The column number of this frame.

• #context(context_lines : Int32 | Nil = nil) : Tuple(Array(String), String, Array(String)) | Nil

  Returns a tuple consisting of 3 elements - an array of context lines before the #lineno, line at #lineno, and an array of context lines after the #lineno.

• #context_hash(context_lines : Int32 | Nil = nil) : Hash(Int32, String) | Nil

  Returns hash with context lines, where line numbers are keys and the lines itself are values.

• #hash(hasher)

  See Object#hash(hasher)

• #in_app? : Bool

  Returns true if this frame originated from the app source code, false otherwise.

• #inspect(io : IO) : Nil

  Appends this struct's name and instance variables names and values to the given IO.

• #lineno : Int32 | Nil

  The line number of this frame.

• #method : String

  The method of this frame (such as User.find).

• #path : String | Nil

  The file name of this frame (such as app/models/user.cr).

• #relative_path : String | Nil

  Returns:

• #shard_name : String | Nil

  Returns name of the shard from which this frame originated.

• #to_s(io : IO) : Nil

  Reconstructs the frame in a readable fashion.

• #under_src_path? : Bool

  Returns true if #path of this frame is within the configuration.src_path, false otherwise.
