Expand description
An ‘asm’ block represents an opaque set of Fuel VM assembly instructions, embedded in place and intended to be inserted as is into the assembly code generation.
An [AsmBlock] has symbols for arguments and an optional return name and contains a list of
AsmInstruction.
The syntax in Sway for asm blocks is shown by this example, and [AsmBlock] represents it
symbolically:
asm(r1: self, r2: other, r3) {
add r3 r2 r1;
r3: u64
}
