[−][src]Trait ieql::common::compilation::CompilableTo
The CompilableTo<T> trait specifies the compilation interface for each
of IEQL's compilable internals, including Documents and Query groups,
among others.
The fundamental idea of compilation in the Rust IEQL implementation is that
every component of a scan has a certain amount of 'overhead'—that is, logic
that must be repeated. For example, in Patterns, the RegEx must be composed
by the RegEx library into something that can be used to scan text. This is a
relatively expensive operation, and therefore it makes no sense to perform it
multiple times.
In essence, compilation performs the repeated expensive logic for various IEQL components ahead of time to save time later.
Required methods
fn compile(&self) -> Result<T, Issue>
Returns a compiled version of self, without using self.
Importantly, compiling a component will perform a deep clone on that
component. Remember: compilation is expensive!
Implementors
impl CompilableTo<CompiledPattern> for Pattern[src]
fn compile(&self) -> Result<CompiledPattern, Issue>[src]
This function compiles the Pattern into a CompiledPattern by
escaping the RegEx expression as necessary and then compiling it.
impl CompilableTo<CompiledDocument> for Document[src]
fn compile(&self) -> Result<CompiledDocument, Issue>[src]
impl CompilableTo<CompiledDocumentBatch> for DocumentBatch[src]
fn compile(&self) -> Result<CompiledDocumentBatch, Issue>[src]
impl CompilableTo<CompiledQuery> for Query[src]
fn compile(&self) -> Result<CompiledQuery, Issue>[src]
Compiles the Query into a CompiledQuery. Like all compilation
operations, this is expensive.
impl CompilableTo<CompiledQueryGroup> for QueryGroup[src]
fn compile(&self) -> Result<CompiledQueryGroup, Issue>[src]
Compiles the QueryGroup into a CompiledQueryGroup. Like
all compilation operations, this is expensive.
