pub struct LoadingDepthLimiter(Cell<usize>);Expand description
Tracks the number of nested file loads within a document
While loading or rendering a document, various operations may
cause extra files to be read. For example, XML includes, or
<image src="foo.svg">, or loading a CSS stylesheet, or CSS
includes. Librsvg places a limit on the nesting depth, to catch
recursively referenced files. See the description for
limits::MAX_FILE_LOADING_DEPTH.

impl LoadingDepthLimiter
Sourcepub fn increment(&self) -> Result<(), LoadingDepthError>
pub fn increment(&self) -> Result<(), LoadingDepthError>
Increments the depth of loaded files.
Returns an error if the limit is exceeded; in this case the caller should terminate the loading process with an error as quickly as possible.
