Struct bracket::helper::each::Each

pub struct Each;

Iterate an array or object.

Accepts a single argument of the target to iterate, if the target is not an array or object this will return an error.

Each iteration sets a new scope with the local variables:

• @first: If this is the first iteration true.
• @last: If this is the last iteration true.

Note that these variables are set even for objects where iteration order is not guaranteed which can be useful.

For objects the @key variable contains the name of the field; for arrays the @index variable contains the current zero-based index.
