< p > This template provides a convenient way to work with < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > Option< / span > < / span > < / tt > types in Nim. It allows you to execute a block of code (< tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > body< / span > < / span > < / tt > ) only when the < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > Option< / span > < / span > < / tt > is not empty.< / p >
< p > < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > self< / span > < / span > < / tt > is the < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > Option< / span > < / span > < / tt > instance being checked. < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > value< / span > < / span > < / tt > is the variable name to be used within the < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > body< / span > < / span > < / tt > for the unwrapped value. < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > body< / span > < / span > < / tt > is a block of code that is executed only if < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > self< / span > < / span > < / tt > contains a value.< / p >
< p > The < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > value< / span > < / span > < / tt > within < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > body< / span > < / span > < / tt > is automatically unwrapped from the < tt class = "docutils literal" > < span class = "pre" > < span class = "Identifier" > Option< / span > < / span > < / tt > , making it simpler to work with without needing explicit checks or unwrapping.< / p >
< p > Example:< / p >
< p > < pre class = "listing" > < span class = "Keyword" > let< / span > < span class = "Identifier" > myOpt< / span > < span class = "Operator" > =< / span > < span class = "Identifier" > Opt< / span > < span class = "Operator" > .< / span > < span class = "Identifier" > some< / span > < span class = "Punctuation" > (< / span > < span class = "DecNumber" > 5< / span > < span class = "Punctuation" > )< / span >
< span class = "Identifier" > myOpt< / span > < span class = "Operator" > .< / span > < span class = "Identifier" > withValue< / span > < span class = "Punctuation" > (< / span > < span class = "Identifier" > value< / span > < span class = "Punctuation" > )< / span > < span class = "Punctuation" > :< / span >
< span class = "Identifier" > echo< / span > < span class = "Identifier" > value< / span > < span class = "Comment" > # Will print 5< / span >
< / pre > < / p >
< p > Note: This is a template, and it will be inlined at the call site, offering good performance.< / p >
