Struct lol_html::MemorySettings [−][src]
Specifies the memory settings for HtmlRewriter
.
Fields
preallocated_parsing_buffer_size: usize
Specifies the number of bytes that should be preallocated on HtmlRewriter
instantiation
for the internal parsing buffer.
In some cases (e.g. when rewriter encounters a start tag represented by two or more input chunks) the rewriter needs to buffer input content.
Internal parsing buffer is used in such cases. Reallocations and, thus, performance degradation can be avoided by preallocating the buffer ahead of time. As a drawback of this approach, every instance of the rewriter will consume the preallocated amount of memory.
It’s up to the user to adjust the limit according to their environment limitations.
Default
1024
bytes when constructed with MemorySettings::default()
.
max_allowed_memory_usage: usize
Sets a hard limit in bytes on memory consumption of a HtmlRewriter
instance.
Rewriter’s write
and end
methods will error if this limit is exceeded.
Note, that value doesn’t reflect the exact threshold after which the rewriter will bailout. It is impossible to account for all the memory consumed without a significant performance penalty. So, instead, we try to provide the best approximation by measuring the memory consumed by internal buffers that grow depending on the input.
Default
std::usize::MAX
when constructed with MemorySettings::default()
.
