pub struct Position { /* fields omitted */ }
Expand description
A location (line number + character position) in the input script.
In order to keep footprint small, both line number and character position have 16-bit resolution,
meaning they go up to a maximum of 65,535 lines and 65,535 characters per line.
Advancing beyond the maximum line length or maximum number of lines is not an error but has no effect.
A Position
representing the first position.
Create a new Position
.
line
must not be zero.
If position
is zero, then it is at the beginning of a line.
Panics if line
is zero.
Create a new Position
.
If line
is zero, then None
is returned.
If position
is zero, then it is at the beginning of a line.
Get the line number (1-based), or None
if there is no position.
Get the character position (1-based), or None
if at beginning of a line.
Is this Position
at the beginning of a line?
