/**
* SECTION:ide-debugger-breakpoints
* @title: IdeDebuggerBreakpoints
* @short_title: A collection of breakpoints for a file
*
* The #IdeDebuggerBreakpoints provides a convenient container for breakpoints
* about a single file. This is useful for situations like the document gutter
* where we need very fast access to whether or not a line has a breakpoint set
* during the rendering process.
*
* At it's core, this is a sparse array as rarely do we have more than one
* cacheline of information about breakpoints in a file.
*
* This object is controled by the IdeDebuggerManager and will modify the
* breakpoints as necessary by the current debugger. If no debugger is
* active, the breakpoints are queued until the debugger has started, and
* then synchronized to the debugger process.
*
* Since: 3.32
